PART I

Item 1.

Business

Unless otherwise indicated, all references in this report to the “Company”, “we”, “us”, “our”, and “Cyanotech” refer to Cyanotech Corporation and its wholly owned subsidiary, Nutrex Hawaii, Inc. (“Nutrex Hawaii” or “Nutrex”), a Hawaii corporation.

General

We are a global leader in premium quality, sustainable microalgae cultivation, producing high-value natural ingredients and dietary supplement products for health and wellness. Incorporated in 1983, we are guided by the principle of providing beneficial, quality microalgal products for health and human nutrition in a technology enabled, reliable and environmentally sensitive operation. We are Good Manufacturing Practices ("GMP") certified by Merieux NutriSciences, reinforcing our commitment to quality in our products, quality in our relationships (with our customers, suppliers, employees and the communities we live in), and quality of the environment in which we work. Our products include:

	●	BioAstin® Hawaiian Astaxanthin® - a powerful, natural antioxidant clinically studied to support and maintain the body’s natural inflammatory response, to enhance skin, and to support eye, joint, brain and immune health†. It has expanding applications as a human dietary supplement and dietary ingredient; and
	●	Hawaiian Spirulina Pacifica® - a nutrient-rich superfood dietary supplement clinically supported for natural energy, immune system support, cardiovascular health and as a concentrated source of protein, antioxidant carotenoids, and essential nutrients†

†These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Microalgae are a diverse group of microscopic plants that have a wide range of physiological and biochemical characteristics and contain, among other things, high levels of natural protein, amino acids, vitamins, pigments and enzymes. Microalgae have the following properties that make commercial production attractive: (1) microalgae grow much faster than land grown plants, often up to 100 times faster; (2) microalgae have uniform cell structures with no bark, stems, branches or leaves, permitting easier extraction of products and higher utilization of the microalgae cells; and (3) the cellular uniformity of microalgae makes it practical to control the growing environment in order to optimize a particular cell characteristic. Efficient and effective cultivation of microalgae requires consistent light, warm temperatures, low rainfall and proper chemical balance in a very nutrient-rich environment, free of environmental contaminants and unwanted organisms. This is a challenge that has motivated us to design, develop and implement proprietary production and harvesting technologies, systems and processes in order to commercially produce human dietary supplement products derived from microalgae.

Our production of these products at our 96-acre facility on the Kona Coast of the island of Hawaii provides several benefits. We selected the Keahole Point location in order to take advantage of relatively consistent warm temperatures, sunshine and low levels of rainfall needed for optimal cultivation of microalgae. This location also offers us access to cold deep ocean water, drawn from an offshore depth of 2,000 feet, which we use in our Ocean-Chill Drying system to eliminate the oxidative damage caused by standard drying techniques and as a source of trace nutrients for microalgal cultures. The area is also designated a Biosecure Zone, with tight control of organisms allowed into the area and free of genetically modified organisms ("GMO"). We believe that our technology, systems, processes and favorable growing location generally permit year-round harvest of our microalgal products in a cost-effective manner.

Our Business

We operate entirely in one operating segment, the cultivation and production of microalgae into high-value, high-quality natural health and nutrition products. We cultivate, on a large-scale basis, two microalgal species from which our two major product lines, natural astaxanthin products and spirulina products, are derived. We record revenue and cost of sales information by product category, but do not record operating expenses by such product category.

Table of Contents

The following table sets forth, for the two fiscal years ended March 31, the net sales contributed by each of our major product lines and extraction and research and development (“R&D”) services:

	Net Sales

Hawaiian Spirulina Pacifica®		7,628		7,351
Contract extraction and R&D services		849		616
Total	$	24,215	$	23,071

Cost of sales for contract extraction and R&D services for the years ended March 31, 2025 and 2024 were $634,000 and $358,000, respectively.

Natural Astaxanthin Products

We commenced commercial production of natural astaxanthin in 1997 and in 1999 BioAstin®, our natural astaxanthin product was cleared for sale in the U.S. Dietary Supplement market, and in 2007, was approved for sale in Europe. Astaxanthin represented approximately 65% of our net sales in the fiscal year ended March 31, 2025. Astaxanthin’s antioxidant properties are believed to surpass many of the antioxidant properties of vitamin C, vitamin E, beta-carotene and other carotenoids. Independent scientific studies indicate that in certain models, natural astaxanthin has up to 100 times the antioxidant activity of vitamin E and 4 times the antioxidant activity of beta-carotene. In addition, a growing body of scientific literature suggests that natural astaxanthin has beneficial properties as an anti-inflammatory, with additional benefits for joint, skin, eye and immune health.

BioAstin® is generally recognized as safe ("GRAS") as determined by the United States Food and Drug Administration ("FDA"). Our all natural BioAstin® is cultivated without the use of herbicides or pesticides and is not genetically modified ("non-GMO"). In fiscal 2012, we applied for a new dietary ingredient ("NDI"), with the United States FDA, providing for a daily dosage of 12mg of astaxanthin which was reviewed without comment. BioAstin® holds several independent third-party quality certifications including: iGen Non-GMO, Gluten Intolerance Group’s Gluten Free, Detox Project Glyphosate Free, Informed Choice, and Halal and Vegan.org for vegan products, that were products produced up to and including the fiscal year ended March 31, 2025.

We produce natural astaxanthin from Haematococcus pluvialis microalgae grown in a combination of fresh water and a metered amount of nutrient-rich deep ocean water (containing essential trace elements), drawn from a depth of 2,000 feet below sea level, supplemented with nutrients. As these algae are extremely susceptible to contamination by unwanted algae, protozoa and amoebae, we developed a proprietary system known as the PhytoDome Closed Culture System or PhytoDome CCS to overcome this problem. Using this proprietary system at the early culture stage, we have generally been able to grow consistently large volumes of contaminant-free Haematococcus culture, subject to quarterly seasonality.

For the final stage of cultivation, the Haematococcus algae is transferred to open ponds where an environmental stress is applied causing the algae to form spores which accumulate high levels of astaxanthin. The astaxanthin crop in each pond is circulated by paddlewheels to keep an even blend of nutrients in suspension and a uniform exposure of the algae to sunlight, which is a major component of cultivation. Once ready for harvest, the media containing these spores is transported through underground pipes to our astaxanthin processing building where the culture media and algal spores are separated. Astaxanthin is produced in a batch-mode and each cultivation pond must be completely drained and thoroughly cleaned between cycles.

The harvested algal spores are dried to flakes or a fine powder. During processing, the spores are cracked in a proprietary system to assure efficient extraction of astaxanthin. Natural astaxanthin is processed further utilizing a high-pressure supercritical carbon dioxide extraction process at our facility in Kona. The resulting product is a water insoluble lipid extract used in the production of gelcaps.

All natural astaxanthin products undergo a prescribed set of microbiological food product tests to ensure safety and quality. We use third party contract manufacturers for the encapsulation, molding of gummies and packaging of gelcaps and gummies. All third-party contract manufacturers are audit inspected by our Quality Department and are required to comply with the FDA GMP regulations. These contract manufacturers hold independent third party GMP certifications.

BioAstin® is sold primarily as a packaged consumer product through Nutrex Hawaii to natural product distributors, retailers and online channels, or directly to consumers. It is also sold in liquid lipid form as a raw ingredient to dietary supplement manufacturers, health food formulators and cosmetic manufacturers. BioAstin® gelcaps are sold in bulk quantities to distributors. We sell BioAstin® consumer products in gelcap form, including a vegan gelcap, and condition specific health formats and in 2024, we introduced sugar-free and vegan gummies enhanced with Vitamin D3.

BioAstin® competes directly with similar products marketed by other manufacturers including Fuji Chemical of Japan, Algalif of Iceland, AlgaTechnologies of Israel and BGG of China. In the general category of dietary supplements, BioAstin® also competes with a variety of vitamins, dietary supplements and other antioxidant products available to consumers. The dietary supplement products market is highly competitive and includes international, national, regional and local producers and distributors, many of whom have greater resources than we have, and many of whom offer a greater variety of products.

The potential benefits of astaxanthin to human health are continuing to emerge. As one of the most potent and bioactive biological antioxidants found in nature, the number of potential roles of natural astaxanthin for human health is growing. Much research has been published in recent years on the beneficial roles of antioxidants in our health, in the aging process and on specific health conditions. The full efficacy of BioAstin® as a human nutraceutical supplement requires further significant clinical study. Independent antioxidant research and prior clinical trials show promising human applications.

Spirulina Products

We have been producing a strain of spirulina microalgae marketed as Hawaiian Spirulina Pacifica® since 1984. Hawaiian Spirulina Pacifica® represents approximately 32% of our net sales in the fiscal year ended March 31, 2025. Hawaiian Spirulina Pacifica® is a nutrient-rich superfood dietary supplement, proving a plant-based, highly absorbable source of protein, natural beta-carotene, mixed carotenoids, B vitamins, gamma linolenic acid, essential amino acids and other phytonutrients.

Hawaiian Spirulina Pacifica® is produced in three forms: powder and tablets, and in 2024, we introduced gummies. Powder is used as an ingredient in dietary supplements and health beverages. Powder, tablets and gummies are consumed as a daily dietary supplement. All forms are sold in bulk quantities and as packaged consumer products under the Nutrex Hawaii label and as private label consumer packaged products.

Hawaiian Spirulina Pacifica® is GRAS for addition to a variety of foods as determined by the United States FDA. Our all natural Hawaiian Spirulina Pacifica® is cultivated without the use of herbicides or pesticides, is Non-GMO Project verified, is certified Kosher by Organized Kashrus Laboratories of Brooklyn, New York and is certified Halal by the Islamic Food and Nutrition Council of America. Hawaiian Spirulina Pacifica® holds additional independent third-party quality certifications including: Gluten Intolerance Group’s Gluten Free, Detox Project Glyphosate Free, and is certified Vegan through Vegan.org. It also holds the highest, Class A safety rating from the Dietary Supplement Information Expert Committee (DSI-EC) of the United States Pharmacopeia.

Our Hawaiian Spirulina Pacifica® is cultivated in fresh water and supplemented with other major required nutrients. We recycle the media and all freshwater input in our spirulina production process.

The spirulina crop in each pond is circulated by paddlewheels to keep an even blend of nutrients in suspension and a uniform exposure of the algae to sunlight, which is a major component of cultivation. Our ponds are engineered to maintain the right media depth for sunlight to permeate each crop completely, facilitating rapid growth. The design of our cultivation ponds promotes efficient growing conditions, allowing the Hawaiian Spirulina Pacifica® algae to reproduce rapidly. Each pond can be harvested, on average, in nine days.

Once ready for harvest, a majority of the spirulina algae are pumped from a pond to our processing building where the crop is separated from the culture media. The culture remaining in the ponds serves as an inoculum for the next growth cycle. Harvested spirulina is washed with fresh water and filtered before moving to the drying stage. Culture media separated from spirulina algae during processing are conserved and recycled. Our Integrated Culture Biology Management (“ICBM”) technology for microalgae cultivation has proven to be a reliable and stable operating environment, allowing us to grow and harvest spirulina without significant contamination by unwanted microorganisms and without associated loss of productivity.

Hawaiian Spirulina Pacifica® powder is dried via our low-oxygen Ocean-Chill Drying process, thereby preserving high levels of antioxidant carotenoids and other nutrients sensitive to heat and oxygen. The rapid drying process results in a dark green powder. Spirulina powder is generally difficult to form into tablets, and most tablet manufacturers either add high amounts (from 10% to 30%) of inert substances to “glue” the tablet together or use a heat granulation process that destroys nutrients. In contrast, our Hawaiian Spirulina Pacifica® tablets contain a maximum of 2% of such substances and are produced in cold press compression tablet-making machines.

Each production lot of Hawaiian Spirulina Pacifica® is sampled and subjected to thorough quality control analyses including testing for moisture, carotenoids, minerals, color and taste, among others. Further, each lot of our Hawaiian Spirulina Pacifica® undergoes a prescribed set of microbiological tests to ensure the absence of contaminants, including total aerobic bacteria, coliform bacteria, Salmonella and E. coli. The Hawaiian Spirulina Pacifica® powder, tablets and gummies are packaged to extend shelf life and ensure product freshness. Our packaged consumer products are bottled and labeled by third party contractors in California. These contractors are subject to regular government inspections and hold Drug Manufacturing Licenses & Processed Food Registrations with the State of California Department of Health. These contract manufacturers hold independent third party GMP certifications.

Table of Contents

The majority of our bulk spirulina is sold to international health food manufacturers and formulators, many of whom identify and promote our Hawaiian Spirulina Pacifica® in their products. Such customers purchase bulk powder or bulk tablets and package these products under their brand label for sale to the health and natural food markets in their countries. Some of the brands produced by these customers are marketed and sold in direct competition with the packaged consumer products sold through our Nutrex Hawaii subsidiary in international channels. In the domestic market, Nutrex Hawaii packaged consumer products are sold through natural product distributors, retailers and online channels, or directly to consumers. In selected international markets, we have exclusive sales distributors for both our bulk and packaged consumer products.

Our Hawaiian Spirulina Pacifica® products compete with a variety of vitamins, dietary supplements, other algal products and similar nutritional products available to consumers. The dietary supplement products category is highly competitive and includes international, national, regional and local producers and distributors, many of whom have greater resources than Cyanotech and many of whom offer a greater variety of products.

Our direct competition in the spirulina market is currently from Parry Nutraceuticals, a division of Murugappa Group of India, Earthrise Nutritionals, LLC and several farms in China.

In addition, there are numerous other smaller farms throughout the world. As one of the largest producers of spirulina, and the only producer of spirulina in Hawaii, our challenge is to increase our market share among customers who seek the high-quality products we produce while concurrently adjusting our product mix to meet our revenue and profitability targets.

Contract Extraction and Research and Development Services (“contract services”)

As a result of capacity improvements that we made to our best-in-class, 1,000 bar, supercritical carbon dioxide extraction system, we began offering contract extraction services to third-party producers of astaxanthin biomass in fiscal 2019.

Due to our knowledge and expertise in cultivating microalgae combined with excess production capacity, we began offering R&D services to third parties in fiscal 2023.

Total contract services and R&D services revenue represented approximately 4% and 3% of our net sales in fiscal years ended March 31, 2025 and 2024, respectively.

Major Customers

Two customers individually accounted for 31% and 10% of our total net sales for the fiscal year ended March 31, 2025. Two customers individually accounted for 34% and 17% of our total net sales for the fiscal year ended March 31, 2024.

Research and Development

Our expertise for many years has been in the development of efficient, stable and cost-effective production systems for microalgal products. We have learned production levels from our systems may not be sustainable across periods of days, weeks, or even months. Accordingly, we typically investigate each specific microalgae identified in the scientific literature for potentially marketable products and for solutions to production stability and efficiency challenges and then strive to develop the technology to grow such microalgae on a commercial scale or to incorporate procedures or technology to improve production stability and efficiency. Successful microalgal product developments and technical solutions are highly uncertain and dependent on numerous factors, many beyond our control. Products and solutions or improvements that appear promising in early phases of development may be found to be ineffective, may be uneconomical because of manufacturing costs or other factors, may be precluded from commercialization due to the proprietary rights of other companies, or may fail to receive necessary regulatory approvals. Our R&D expenses were $0.4 million and $0.7 million for the years ended March 31, 2025 and 2024, respectively.

Patents, Trademarks and Licenses

We previously held four United States patents: one on aspects of our production methods and three relating to usage of our BioAstin® products. Our production method patent, which was directed to microalgae production technology, expired in April 2016. Our other three patents, which were utility patents relating to the use of astaxanthin in our BioAstin® products, expired in December 2019, February 2020 and April 2020.

Although we view our proprietary rights as important, we currently believe that a loss of patent rights is not likely to have a material adverse effect on our present business as a whole. Instead, our commercial results mainly depend upon our trade secrets, know-how, other non-patent proprietary rights, customer relationships, our climate and our location. As a result, we feel that our competitors will not be able to implement competing technology covered by our former patents without our same combination of non-patented attributes.

Table of Contents

We have registered trademarks in the U.S. and in some foreign markets, such as the European Union. Our operations are not dependent upon any single trademark, although some trademarks are identified with a number of our products and are important in the sale and marketing of such products.

Regulations

Several governmental agencies regulate various aspects of our business and our products in the United States, including the FDA, the Federal Trade Commission (“FTC”), the Consumer Product Safety Commission, the State of Hawaii Department of Health, the Department of Agriculture, the Environmental Protection Agency (“EPA”), the United States Postal Service, state attorney general offices and various agencies of the states and localities in which our products are sold. We believe we are in compliance with all material government regulations which apply to our products and operations. However, we are not able to predict the nature of any future laws, regulations, interpretations or applications, nor can we predict what effect future changes would have on our business.

Our international customers are subject to similar governmental agency regulations in their various geographic regions. Compliance by our customers with such local regulations is beyond our control and we cannot predict their ability to maintain such compliance. However, we strive to assist our customers in meeting local regulations pertaining to the use and sale of our products whenever possible.

Environmental Matters

In 2002, we were issued under the Endangered Species Act (“ESA”) an Incidental Take Permit (“ITP”) by the United States Department of Interior Fish and Wildlife Service (“FWS”). The ESA defines “incidental take” as “incidental to, and not for the purpose of, the carrying out of an otherwise lawful activity.” This permit authorizes incidental take of the endangered Hawaiian stilt (Himantopus mexicanus knudseni) that is anticipated to occur as a result of ongoing operations and maintenance at our Kona facility. As a mandatory component for the issuance of such permit, we submitted and maintain a Habitat Conservation Plan (“HCP”) to ensure that the effects of the permitted action on listed species are adequately minimized and mitigated.

The HCP called for the creation of a nesting and breeding ground for the Hawaiian stilt to offset any take activity. We have complied with these requirements since 2002. The breeding program was so successful that the increase in the Hawaiian stilt population in the area became a potential hazard for the adjacent State airport facility. We disassembled the stilt habitat and are mitigating “take” by using standard non-lethal hazing devices to discourage nesting and breeding.

A requirement of the ITP is to provide insurance coverage for funding the project for the term of the ITP. Our insurance broker was unable to locate an underwriter who would provide such a bond. As permitted by law, the FWS waived this requirement recognizing that this HCP did not involve a significant capital expenditure. However, under Hawaii state law, no waiver provision is available. A new ITP was issued by the US Department of the Interior effective June 1, 2019; the permit expires June 1, 2035.

Employees

As of March 31, 2025, we employed 83 people. Of the total, 32 are involved in harvesting, production and quality, with the remainder in maintenance, shipping, sales, administration and support. None of our employees are subject to collective bargaining agreements. Management believes that its relations with employees are good.

General economic conditions affecting the dietary supplement industry and various operating factors and the health of the economy in general may affect our business and operating results.

Our operations and financial performance may be affected by general economic conditions such as volatility and disruptions, diminished liquidity and credit market conditions and the level of consumer confidence. Inflation may affect our business by reducing consumer spending, which may impact sales growth and our underlying costs. We have observed increased inflation during the past few years with varying impacts on our business. If increases in energy costs and inflationary trends continue, our business and operating results could be adversely affected. We may also experience adverse impacts to our business as a result of consumers’ perceptions of the economy, and a decrease in their personal financial condition could hurt overall consumer confidence and reduce demand for our products. Consumers may reduce non-essential items, purchase value-oriented products or increasingly rely on dietary supplement discounters in an effort to secure their products, which could impact our operating results. In addition, adverse changes in the U.S. economy, consumer confidence and economic conditions could have an adverse effect on our operating results.

Public health crises may adversely affect our business, results of operations, financial condition, liquidity, and cash flow.

Future pandemics or public health crises and the measures taken in response could adversely impact our business, financial condition and results of operation and heighten many of the other risks described throughout this report, including but not limited to those relating to our operating strategy, supply chain, increased labor costs, availability of labor, disruption in operations, loss of key employees, our indebtedness, and general economic conditions. We may also experience a negative impact from government mandated restrictions and community response measures which may disrupt our business and thus negatively impact our financial results.

Our production of algae involves an agricultural process, subject to such risks as weather, disease, contamination, water availability and climate change.

The production of our algae products involves complex agricultural systems with inherent risks including weather, disease, and contamination. These risks are unpredictable and also include such elements as the control and balance of necessary nutrients and other factors. The efficient and effective cultivation of microalgae requires consistent light, warm temperatures, low rainfall and proper chemical balance in a very nutrient-rich environment.

If the chemical composition of a pond changes from its required balance, unusually high levels of contamination due to the growth of unwanted organisms or other biological problems may occur and would result in a loss of harvestable output. These often arise without warning and sometimes there are few or no clear indicators as to appropriate remediation or corrective measures. We believe that our technology, systems, processes and favorable growing location generally permit year-round harvest of our microalgal products in a cost-effective manner. However, environmental factors cannot be controlled in an open-air environment, therefore, we cannot, and do not attempt to, provide any form of assurance with regard to our systems, processes, location, or cost-effectiveness. In the event that we need to take steps to correct any chemical imbalance or contamination of our ponds, including by re-inoculating the ponds, such measures may not be effective and could interrupt production. To the extent that our production is negatively impacted by environmental factors, we may be unable to fill large orders for one or more months until such time that production improves. The efficient and effective cultivation and processing of microalgae requires a consistent supply of fresh water and cold ocean water. If the availability and or quality composition of water changes from its required levels, problems may occur that could result in a loss of harvestable output.

Hawaii from time to time has experienced shortages of water, electric power and fuels. Future shortages could disrupt our operations and could result in additional expense. Our astaxanthin is cultivated in a combination of fresh water and deep ocean water. In the case of deep ocean water, although abundantly available at this location, the facility to pump and deliver the water to our location is owned by the State of Hawaii. The State of Hawaii sets the price for deep ocean water annually based on its cost to deliver the water. Any significant increase in the price could adversely affect our business. The availability and price of water could also be impacted by a significant population growth in the region as well as throughput constraints on the water delivery infrastructure. In June 2017, several fresh-water pumps owned by the County of Hawaii were disabled, and the county instituted restrictions on fresh water supply. We have adopted several water savings strategies to mitigate this challenge, but there is no guarantee that they will be effective or that they will not have unforeseen negative effects on the growth of spirulina. If we are unable to obtain enough fresh water at reasonable prices to cultivate our products, our business could be negatively impacted.

Climate change has not impacted weather at our location on Hawaii Island. We have experienced both dry and wet periods of weather, but it has not affected production. However, there can be no guarantee that future climate change will not affect our production.

There is risk in operating entirely in one business segment such as the cultivation and production of microalgae at a single production facility.

Single location agricultural and production facilities do not provide the protections and assurances afforded by operations in two or more widely separated locations. Our single location in Hawaii is susceptible to unfavorable weather patterns and catastrophic natural disasters such as earthquakes, tsunamis, hurricanes and volcanic eruptions. In the event of a natural disaster or localized extended outages of critical utilities or transportation systems, we could experience a significant business interruption. Also, a single agricultural facility provides limited biologic diversity protection against invasive, mutant, or harmful organisms.

Our facilities in Hawaii are located adjacent to a major airport, and an aircraft disaster could disrupt our operations.

Our production facility and corporate headquarters in Hawaii are located adjacent to the Keahole International Airport. In the event of an aircraft disaster, we could experience a significant business interruption, including loss of water, electrical and communication services as well as inability to access our facilities.

Unfavorable publicity or consumer perception of our products and any similar products distributed by other companies could have a material adverse effect on our business.

The dietary supplements market is highly dependent upon consumer perception regarding the safety, efficacy and quality of dietary supplements. Consumer perception of our products can be significantly influenced by scientific research and findings, as well as by national media attention and other publicity regarding the consumption of dietary supplements. There can be no assurance that future research or publicity will be favorable to the dietary supplements market or any product in particular, or consistent with earlier publicity. Our dependence on consumer perception means that any adverse reports, findings or publicity, whether or not accurate or with merit, could have a material adverse effect on the demand for our products and on our results of operations, cash flow and financial condition.

We may become subject to legal proceedings.

We may become subject to claims and legal proceedings in the ordinary course of business. The costs of such proceedings could vary from quarter to quarter based on the status of the proceedings and could have a material impact on our results in any given quarter.

The dietary supplement products industry is extremely competitive. Many of our significant competitors have greater financial and other resources than we do, and one or more of these competitors could use their greater resources to gain market share at our expense.

The dietary supplement products market includes international, national, regional and local producers and distributors, many of whom have substantially greater production, financial, research and development, personnel and marketing resources than we do, and many of whom offer a greater variety of products.

As a result, each of these companies could compete more aggressively and sustain that competition over a longer period of time than we could. Our lack of resources relative to our significant competitors may cause us to fail to anticipate or respond adequately to development of new products and changing consumer demands and preferences or may cause us to experience significant delays in obtaining or introducing new or enhanced products. These failures or delays could reduce our competitiveness and cause a decline in our market share and sales. Increased competition in our industry could result in price reductions, reduced gross profit margin or loss of market share, any of which could have a material effect on our business, results of operations and financial condition.

We depend heavily on the unique abilities and knowledge of our officers and key personnel. If we are unable to recruit and retain key personnel, we may be unable to achieve our goals.

Our success depends, to a significant extent, upon the services of our officers and key personnel, including qualified management, professional, scientific, and technical operating staff. The loss of any such personnel or the delay in the replacement of such personnel could significantly delay the achievement of our business objectives and could adversely affect our ability to do business or provide the management needed. Attracting permanent skilled executives in Hawaii can be difficult due to limited qualified local applicants. If we are unable to attract qualified candidates, or if the search process takes longer than expected, it could adversely impact our business.

Labor shortages could restrict our ability to operate or grow our business or result in increased labor costs that could adversely affect our results of operations.

Our success depends in large part on our ability to attract, retain, train, manage and engage employees. The COVID-19 pandemic had a significant impact on the labor market. Post pandemic, labor shortages have affected our ability to hire or re-hire employees. For a large percentage of our business, our activities need to be performed in person at Kona. Our labor pool on the island of Hawaii is limited. Because payroll costs are a major component of the operating expenses a shortage of labor could also require higher wages that would increase labor costs, which could adversely affect our results of operations.

Our operations are vulnerable because we have limited personnel and redundancy and backup systems in our data management function.

Our internal order, inventory and product data management system is an electronic system through which orders are placed for our products and through which we manage product pricing, shipment, returns and other matters. This system’s continued and uninterrupted performance is critical to our day-to-day business operations. Despite our precautions, unanticipated interruptions in our computer and telecommunications systems have, in the past, caused problems or stoppages in this electronic system. These interruptions, and resulting problems, could occur again in the future. We also have limited personnel available to process purchase orders and to manage product pricing and other matters in any manner other than through this electronic system. Any significant interruption or delay in the operation of this electronic management system could cause a decline in our sales and profitability.

The loss of a major customer, or a change in their procurement practices, could result in a material reduction in our revenues and profitability.

Our top ten customers generated 70% and 69% of our net sales for fiscal years 2025 and fiscal 2024, respectively. Two customers individually accounted for 31% and 10%, and 34% and 17% of our total net sales in the fiscal years ended March 31, 2025 and 2024, respectively. Accordingly, the loss of one or more of those customers or a substantial decrease in such customers' purchases from us could result in a material reduction in our revenues and profitability.

We could be subject to breaches of our information technology systems, which could damage our reputation and customer relationships. Such breaches could subject us to significant reputational, financial, legal, and operational consequences.

Our business relies on information systems to obtain, rapidly process, analyze and manage data to, among other things, facilitate the purchase and distribution of inventory items through numerous distributors; receive, process and ship orders on a timely basis; accurately bill and collect from customers; process payments to suppliers; and provide technical support to our customers.

A cyber-attack that bypasses our security, or employee error, malfeasance or other disruptions that cause a security breach could lead to a material disruption of our information systems and/or the loss of business information. Cyber-attacks are expected to accelerate on a global basis and threats are increasingly sophisticated in using techniques and tools, including artificial intelligence, that are designed to circumvent security controls and evade detection. Such an attack could result in, among other things, the theft, destruction, loss, misappropriation or release of confidential data and intellectual property; operational or business delays; liability for a breach of personal information belonging to our customers or our employees; and damage to our reputation any of which could have a material adverse effect on our business, financial condition, and results of operations. In the event of an attack, we would be exposed to a risk of loss or litigation and possible liability, including under laws that protect the privacy of personal information.

To date, the risks posed by such cybersecurity threats have not materially affected us or our business strategy, results of operations or financial condition, and as of the date of this report, we are not aware of any material risks from cybersecurity threats that are reasonably likely to do so, but there can be no assurance that we will not be materially affected by such risks in the future.

Compliance with new and existing government regulations could increase our costs significantly and adversely affect our results of operations.

The processing, formulation, manufacturing, packaging, labeling, advertising and distribution of our products are subject to federal laws and regulation by one or more federal agencies, including the FDA, the FTC, the United States Department of Agriculture (“USDA”) and the EPA. These activities are also regulated by various state, local and international laws and agencies of the states and localities in which our products are sold. Regulations may prevent or delay the introduction, or require the reformulation, of our products, which could result in lost sales and increased costs to us. A regulatory agency may not accept the evidence of safety for any new ingredients that we may want to market, may determine that a particular product or product ingredient presents an unacceptable health risk, may determine that a particular statement of nutritional support on our products or that parties use on the products we manufacture for them, or that we want to use on our products or that third parties want to use on the products we manufacture for them, is an unacceptable drug claim or an unauthorized version of a food “health claim”. A regulatory agency may determine that particular claims are not adequately supported by available scientific evidence. Any such regulatory determination would prevent us from marketing particular products or using certain statements on those products, which could adversely affect our sales of those products.

Additional or more stringent laws and regulations of dietary supplements and other products have been considered from time to time. These developments could require reformulation of some products to meet new standards, recalls or discontinuance of some products not able to be reformulated, additional record-keeping requirements, increased documentation of the properties of some products, additional or different labeling, additional scientific substantiation, or other new requirements. Any of these developments could increase our costs significantly. In addition, regulators' evolving interpretation of existing laws could have similar effects.

If we fail to comply with the reporting obligations of the Exchange Act and Section 404 of the Sarbanes Oxley Act or fail to maintain adequate internal control over financial reporting, our business, financial condition, and results of operations, and investors’ confidence in us, could be materially and adversely affected.

As a public company, we are required to comply with the periodic reporting obligations of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including preparing annual reports, quarterly reports, and current reports. Our failure to prepare and disclose this information in a timely manner and meet our reporting obligations in their entirety could subject us to penalties under federal securities laws and regulations of the OTCQB Market (“OTCQB”), expose us to lawsuits, and restrict our ability to access financing on favorable terms, or at all.

In addition, pursuant to Section 404 of the Sarbanes Oxley Act, we are required to evaluate and provide a management report of our systems of internal control over financial reporting. During the course of the evaluation of our internal control over financial reporting, we could identify areas requiring improvement and could be required to design enhanced processes and controls to address issues identified through this review. This could result in significant delays and costs to us and require us to divert substantial resources, including management time, from other activities. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with the Sarbanes Oxley Act. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent fraud. Any failure to maintain compliance with the requirements of Section 404 on a timely basis could result in the loss of investor confidence in the reliability of our financial statements, which in turn could, negatively impact the trading price of our stock, and adversely affect investors’ confidence in the Company and our ability to access capital markets for financing.

Our two largest shareholders own a substantial portion of our common stock and could exert substantial influence over our business, particularly if any of them choose to work together.

Our two largest shareholders collectively own approximately 37.6% of our common stock. According to publicly filed beneficial ownership reports, as of the respective dates of such reports, Michael Davis, chairman of our board of directors, beneficially owned 1,788,756 of shares representing a 24.8% beneficial ownership and the Rudolf Steiner Foundation ("RSF") beneficially owned 917,133 shares representing a 12.7% beneficial ownership. The shares held by RSF were originally donated by a foundation affiliated with Mr. Davis or acquired from the proceeds of donations made by that foundation. In addition, Mr. Davis and RSF filed a Schedule 13D with the SEC on March 17, 2017, announcing the formation of a “group” among the two of them and certain of Mr. Davis’ affiliates under Section 13 of the Exchange Act. As part of the agreement between Mr. Davis and RSF, RSF has agreed not to sell, transfer or otherwise dispose of any of its shares in the Company unless RSF provides concurrent written notice to an affiliate of Mr. Davis and the Company at least three days prior to the consummation of any such sale, transfer or other disposition. On August 24, 2023, 424,621 shares of our common stock owned by Skywords Family Foundation, Inc. (“Skywords”) was donated to Ginungagap Foundation (“Ginungagap”), a Delaware corporation, recognized as a tax-exempt organization. Mr. Davis serves as the President of both Skywords and Ginungagap and has recused himself from all matters related to the common stock owned by Ginungagap, including, without limitation, decisions to vote or dispose of Cyanotech common stock. Along with this recusal, the formation of this “group” was dissolved. In addition, on April 12, 2019, the Company borrowed $1.5 million from an entity affiliated with Mr. Davis pursuant to an unsecured promissory note. In April 2021, the Company amended the loan, which extended the maturity date to April 2024, converted $500,000 into revolving loans, adjusted the interest rate to reflect a floor of 5%, and granted a security interest in substantially all of the Company’s personal property assets, subject to limited exceptions. In December 2022, the Company amended the promissory note which extended the maturity date to April 2025 and increased the revolving line amount from $0.5 million to $1.0 million. In August 2023, the Company amended the loan to increase the revolving line amount from $1.0 million to $2.0 million. In August 2024, the Company further amended the loan to increase the revolving line amount from $2.0 million to $4.0 million and extend the maturity date to April 2026. As of both March 31, 2025 and 2024, $1.0 million remained due under this promissory note, and as of March 31, 2025 and 2024, $3.0 million and $1.25 million, respectively, were outstanding on the revolving line, respectively.

Our significant stockholders, particularly if they choose to work together, may have the ability to exert significant influence over our business policies and affairs on matters submitted to our stockholders for approval, such as the election or removal of directors, amendments to our certificate of incorporation, the approval of a business combination or certain corporate financing activities. The interests of our significant stockholders could differ from those of other stockholders in ways that could be adverse to the interests of other shareholders. For example, this concentration of ownership could have the effect of delaying or preventing a change of control of our company even if such a transaction is at a premium to the prevailing market price of our common stock and is supported by other shareholders. Concentration of ownership could also harm the market price of our common stock because investors may perceive disadvantages in owning stock in a company that a substantial portion of common stock is controlled by a small number of stockholders.

Some provisions of our charter documents and Nevada law may discourage an acquisition of us by others, even if the acquisition may be in the best interest of our stockholders.

Provisions in our Restated Articles of Incorporation and Amended and Restated Bylaws, as well as certain provisions of Nevada law, could make it more difficult for a third-party to acquire us, even if doing so may benefit our stockholders. These provisions include the authorization of “blank check” preferred stock, the rights, preferences and privileges of which may be established and shares of which may be issued by our board of directors at its discretion from time to time and without stockholder approval.

Because we are incorporated in Nevada, we may be governed by Nevada’s statutes governing combinations with interested stockholders and control share acquisitions, which may discourage, delay or prevent someone from acquiring us or merging with us, whether or not it is desired by or beneficial to our stockholders. We have not opted out of the application of these laws but may elect to opt out in the future. Under Nevada’s laws governing combinations with interested stockholders, a Nevada corporation may not, in general, engage in certain types of business combinations with any beneficial owner of 10% or more of the corporation’s voting shares or an affiliate of the corporation who at any time within two years immediately prior to the date in question was the beneficial owner of 10% or more of the corporation’s voting shares, unless the holder has held the stock for two years or the board of directors approved the beneficial owner’s acquisition of its shares, the board of directors approved the transaction before the beneficial owner acquired its shares, or holders of at least a majority of the outstanding voting power approve the transaction after the beneficial owner acquired its shares. In addition, Nevada’s control share acquisition laws prohibit a purchaser of the shares of an issuing corporation from voting those shares, under certain circumstances and subject to certain limitations, after crossing specified threshold ownership percentages, unless the purchaser obtains the approval of the issuing corporation’s disinterested stockholders.

Any provision of our Restated Articles of Incorporation or Amended and Restated Bylaws or of Nevada law that is applicable to us that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock in the event that a potentially beneficial acquisition is discouraged and could also affect the price that some investors are willing to pay for our common stock.

A significant or prolonged economic downturn could have a material adverse effect on our results of operations.

Our results of operations are affected by the business activity of our customers who in turn are affected by the level of economic activity in the industries and markets that they serve. A decline in the level of business activity of our clients or the economy as a whole could have a material adverse effect on our revenues and profit margin.

The global cost of oil derived energy impacts us in several ways, and it may hinder our efforts to achieve profitability. Oil prices primarily impact us through the costs of electricity, transportation, materials and supplies which are tied to the cost of oil either directly or indirectly. The return of the high cost of oil on a global basis may signal a prolonged economic downturn resulting in a material adverse effect on our business.

Our quarterly operating results may vary from quarter to quarter, which may result in increased volatility of our share price.

We have experienced, and may in the future continue to experience, fluctuations in our quarterly operating results. These fluctuations could reduce the market price of our common stock. Factors that may cause our quarterly operating results to vary include, but are not limited to:

	●	weather-related cultivation difficulties;
	●	availability and cost of fresh water and ocean water;
	●	any non-routine legal fees;
	●	fluctuations in customer demand;
	●	business decisions of our customers regarding orders for our products;
	●	changes in energy costs;
	●	changes and availability of raw material costs;
	●	production problems which we cannot solve technically or economically;
	●	contamination of our cultivation and production facilities;
	●	effects of weather on our ability to meet customer demand;
	●	timing of promotional activities;
	●	the introduction of new products by us or our competitors;
	●	changes in our pricing policies or those of our competitors;
	●	changes in seasonal and other trends in our customers’ buying patterns;
	●	changes in government regulation, both domestic and foreign;
	●	fluctuation in foreign currency exchange rates;
	●	global economic and political conditions and related risks, including the impacts of a global pandemic and acts of terrorism; and

Table of Contents

●

other factors beyond our control.

A significant portion of our expense levels are relatively fixed. If net sales are below expectations in any given period, the adverse impact on results of operations may be magnified by our inability to reduce expenses quickly enough to compensate for the sales shortfall.

Our global operations expose us to complex management, foreign currency, legal, tax and economic risks, which we may not be able to address quickly and adequately.

Our products are marketed in a number of countries around the world. For the year ended March 31, 2025, approximately 21% of our net sales were from sales to foreign customers. As a result, we are subject to a number of risks which include, but are not limited to:

	●	the burden of complying with a wide variety of national and local laws;
	●	potentially longer payment cycles for foreign sales;
	●	restrictions (government and otherwise) on the movement of cash;
	●	the absence in some jurisdictions of effective laws protecting our intellectual and proprietary property rights, or of enforcement of such laws where they do exist;
	●	changes in government regulations, both domestic and foreign, including changes in trade tariffs;
	●	global economic and political conditions and related risks, including acts of terrorism; and
	●	fluctuations in foreign currency exchange rates.

Climate change initiatives could materially and adversely affect our business, financial condition, and results of operations.

Our manufacturing processes require that we purchase significant quantities of energy from third parties, which results in the generation of greenhouse gases, either directly onsite or indirectly at electric utilities. Both domestic and international legislation to address climate change by reducing greenhouse gas emissions and establishing a price on carbon could create increases in energy costs and price volatility. Considerable international attention is now focused on the development of an international policy framework to address climate change. Proposed and existing legislative efforts to control or limit greenhouse gas emissions could affect our energy source and supply choices as well as increase the cost of energy and raw materials derived from sources that generate greenhouse gas emissions. If our suppliers are unable to obtain energy at a reasonable cost in the future, the cost of our raw materials could be negatively impacted, which could result in increased manufacturing costs.

If we are unable to protect our intellectual property rights or if we infringe upon the intellectual property rights of others our business may be harmed.

We regard our proprietary technology, trade secrets, trademarks and similar intellectual property as important and we rely on a combination of trade secret, contract, copyright and trademark law to establish and protect our rights in our products and technology. However, there can be no assurance that we will be able to protect our technology adequately or that competitors will not be able to develop similar technology independently, particularly following the expiration of our patents relating to the use of astaxanthin. In addition, the laws of certain foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. Litigation in the United States or abroad may be necessary to enforce intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. Such litigation, even if successful, could result in substantial costs and diversion of resources and could have a material adverse effect on our business, results of operations and financial condition. Additionally, if any such claims are asserted against us, we may seek obtaining a license under the third party’s intellectual property rights. There can be no assurance, however, that a license would be available on terms acceptable or favorable to us, if at all.

Our insurance liability coverage is limited and may not be adequate to cover potential losses.

In the ordinary course of business, we purchase insurance coverage (e.g., property and liability coverage) to protect us against loss of or damage to our properties and claims made by third parties and employees for property damage or personal injuries. However, the protection provided by such insurance is limited in significant respects and, in some instances, we have no coverage and certain of our insurance policies have substantial deductibles or limits on the maximum amounts that may be recovered. For example, if a volcanic eruption, tsunami, earthquake or other catastrophic natural disaster should occur, we may not be able to recover all facility restoration costs and revenues lost from business interruption. In addition, we maintain product liability insurance in limited amounts for all of our products involving human consumption; however, broader product liability coverage is prohibitively expensive. Insurers have also introduced new exclusions or limitations of coverage for claims related to certain perils including, but not limited to, mold and terrorism. If a series of losses occurred, such as from a series of lawsuits in the ordinary course of business each of which were subject to the deductible amount, or if the maximum limit of the available insurance were substantially exceeded, we could incur losses in amounts that would have a material adverse effect on our results of operations and financial condition.

Our ability to develop and market new products or modify existing products and production methods may be adversely affected if we lose the services of or cannot replace certain employees knowledgeable in advanced scientific and other fields.

Our products are derived from and depend on proprietary and non-proprietary processes and methods founded on advanced scientific knowledge, skills, and expertise. If the services of employees knowledgeable in these fields are lost and cannot be replaced in a reasonable time frame at reasonable costs, our ability to develop and market new products or modify existing products and production methods would be adversely impacted. At the same time, regulatory compliance surrounding our products and financial matters generally requires a basic knowledge and level of expertise related to production, quality assurance, and financial control. If we lose the services or cannot reasonably replace employees who have the necessary knowledge and expertise our ability to remain in regulatory compliance could be adversely affected.

We may need to raise additional capital in the future which may not be available.

We believe our cash to be provided from operations will be sufficient to meet a portion of our working capital and operating requirements and may have to secure a commitment to fund the remaining gap, but we may experience unexpected reductions in sales due to changes in customer demand, customer purchasing practices, or other factors described in these Risk Factors. If we have an unexpected decline in sales, or we have other unexpected capital needs, we may need to raise additional funds. There is no guarantee that we will be able to secure such funding on acceptable terms, if at all. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our then current stockholders may be reduced. If we raise additional funds through the issuance of convertible debt securities, or through additional debt or similar instruments, such securities, debt, or similar instruments could have rights senior to those of our common stockholders and such instruments could contain provisions restricting our operations. If adequate funds are not available to satisfy either short-term or long-term capital requirements, we may be required to limit operations with adverse results.

We may not be able to refinance, extend or repay our senior indebtedness, which would have a material adverse effect on our financial condition and ability to continue as a going concern.

As of March 31, 2025, we owed First Foundation Bank (the “Bank”) approximately $3.0 million under a Term Loan Agreement dated August 14, 2012, which requires monthly payments of principal and interest until its maturity on August 14, 2032. If we are unable to make payments when due under this agreement, or repay this obligation at maturity, and we are otherwise unable to extend the maturity date or refinance this obligation, we would be in default. We cannot provide any assurances that we will be able to generate the necessary amount of capital to make payments as they become due, or to repay this obligation, or that we will be able to extend the maturity date or otherwise refinance this obligation. In the event of default, the Bank would have the right to exercise its rights and remedies to collect, which would include foreclosing on our assets. Accordingly, a default would have a material adverse effect on our business and, if the Bank exercises its rights and remedies, we would likely be forced to seek bankruptcy protection.

In addition, the agreements governing our indebtedness include certain debt service and other financial covenants that we must satisfy. In previous years, we have defaulted on certain of these covenants and have received waivers of the defaults from the Bank. As of March 31, 2025, the Company was not in compliance with the required debt service coverage and current ratios, however, was in compliance with the third covenant. On June 4, 2025, the Bank issued a letter waiving the covenant violations as of March 31, 2025. As of March 31, 2024, the Company was not in compliance with the debt service coverage and current ratios. On September 12, 2024, the Bank issued a letter waiving the covenant violations as of March 31, 2024. As of March 31, 2023, the Company was not in compliance with the required debt service coverage ratio, but the Bank provided a waiver of the default on June 22, 2023 and implemented an immediate freeze on any and all further advances of the Revolving Credit Agreement (the “Credit Agreement”) through the maturity date. We cannot provide any assurance that the Bank will provide us with a waiver should we not be in compliance in the future. A failure to maintain compliance along with our lender not agreeing to a waiver for the non-compliance would cause the outstanding borrowings to be in default and payable on demand which would have a material adverse effect on us and our ability to continue as a going concern.

We have incurred significant losses in the past. If we incur significant losses in the future, we will experience negative cash flow which may hamper current operations and prevent us from sustaining or expanding our business.

As of March 31, 2025, we had an accumulated deficit of approximately $26.1 million, primarily as a result of current and prior year losses. Historically, we have relied upon cash from operations and financing activities to fund all of the cash requirements of our business. However, no assurance can be provided that we will return to profitability and, even if we do return to profitability, extended periods of profitability and net income do not assure positive cash flows. Future periods of net losses from operations could result in negative cash flow, may cause us to default on certain covenants in our existing debt instruments and may hamper ongoing operations and prevent us from sustaining or expanding our business. We cannot assure you that we will achieve, sustain or increase profitability on a quarterly or annual basis in the future. If we do not achieve, sustain or increase profitability, our business will be adversely affected and our stock price may decline.

Our recurring losses from operations resulting in net cash outflows from operating activities, as well as current cash and liquidity projections, raise substantial doubt about our ability to continue as a going concern.

Based on our recurring losses from operations resulting in net cash outflows from operating activities for the fiscal year ended March 31, 2025, as well as current cash and liquidity projections, we have concluded that there is substantial doubt about our ability to continue as a going concern and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets, or the amounts and classification of liabilities that may result if we do not continue as a going concern. You should not rely on our consolidated balance sheet as an indication of the amount of proceeds that would be available to satisfy claims of creditors, and potentially be available for distribution to shareholders, in the event of liquidation.

Our stock price is volatile, which could result in substantial losses for investors purchasing shares of our common stock.

Stock markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In addition, the average daily trading volume of the securities of small companies can be very low. Limited trading volume of our stock may contribute to its future volatility. Price declines in our common stock could result from general market and economic conditions and a variety of other factors, including any of the following:

	●	volatility resulting from minimal trading activity;
	●	changes in market valuations of similar companies;
	●	stock market price and volume fluctuations generally;
	●	economic conditions specific to the dietary supplement products industry;
	●	economic conditions tied to global resource markets, such as fuel costs;
	●	announcements by us or our competitors of new or enhanced products or of significant contracts, acquisitions, strategic relationships, joint ventures or capital commitments;
	●	fluctuations in our quarterly or annual operating results;
	●	changes in our pricing policies or the pricing policies of our competitors;
	●	changes in foreign currency exchange rates affecting our product costs, pricing or our customers markets;
	●	regulatory developments affecting our specific products or industry; and
	●	additions or departures of key personnel.

The price at which you purchase shares of our common stock may not be indicative of the price that will prevail later in the trading market. You may be unable to sell your shares of common stock at or above your purchase price, which may result in substantial losses to you. As of March 31, 2025, there were approximately 7.2 million shares of our common stock outstanding and stockholders holding at least 5% of our stock, individually or with affiliated persons or entities, collectively beneficially owned or controlled approximately 32.4% of such shares. Sales of large numbers of shares by any of our large stockholders could adversely affect our trading price, particularly given our relatively small historic trading volumes. If stockholders holding shares of our common stock sell, indicate an intention to sell, or if it is perceived that they will sell, substantial amounts of their common stock in the public market, the trading price of our common stock could decline. Moreover, if there is no active trading market or if the volume of trading is limited, holders of our common stock may have difficulty selling their shares.

Recent European Union regulations include stringent requirements for health claims on food and supplement labels.

The European Union has harmonized standards among Member States for health claims on food and supplement labels. The scientific assessment of health claims is performed by the European Food Safety Authority ("EFSA"), an advisory panel to the European Commission. The European Commission will consider the opinions of EFSA in determining whether to include a health claim on a Positive List of permissible claims. Once the list is published, only health claims for ingredients and products included on the list may be used in promotional materials for products marketed and sold in the European Union. This could severely decrease or limit the marketability for our products in this market area. We have implemented strategies that we believe will allow for continued and increasing sales of our products in the European Union. However, there can be no guarantee that such strategies will be successful.

Cybersecurity

Cybersecurity Risk Management and Strategy

We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity and availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response plan and is integrated with our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational and financial risk areas. Our cybersecurity risk management program includes the following key elements:

●

Risk assessments designed to help identify material cybersecurity risks to our critical systems, information, services and our broader enterprise information technology (“IT”) environment;

●

A team comprised of IT personnel responsible for directing (1) our cybersecurity risk assessment processes; (2) our security controls; and (3) our response to cybersecurity incidents;

●

The use of external cybersecurity service providers, where appropriate, to assess, test or otherwise assist with aspects of our cybersecurity processes;

●

Cybersecurity awareness training of employees with access to our systems; and

●

A cybersecurity incident response plan.

During the fiscal year ended March 31, 2025, we have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations, or financial condition. We face certain ongoing risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations or financial condition, as we have described in the Risk Factors section of this Form 10-K.

Cybersecurity Governance

Our Board of Directors considers cybersecurity risk as critical to the enterprise and oversees management’s design, implementation and enforcement of our cybersecurity risk management program, while our executive officers are responsible for the day-to-day management of the material risks. Our Board of Directors receive annual updates, and/or significant updates as needed, on relevant information regarding cybersecurity.

Properties

Our principal facility and corporate headquarters are located at the Natural Energy Laboratory of Hawaii Authority (“NELHA”) at Keahole Point in Kailua-Kona, Hawaii. It encompasses approximately 96 fully developed acres containing microalgal cultivation ponds, processing facilities, research and quality control laboratories, and sales and administrative offices. The property is leased from the State of Hawaii under a 40-year commercial lease expiring in 2035 and a 19-year commercial lease expiring in 2037. Our lessee interest in the NELHA leases is encumbered by a mortgage securing approximately $3.0 million of debt (see Note 5 in the notes to our consolidated financial statements). If we were to require additional land for expansion, we believe that there is sufficient available land at NELHA, provided a revised or additional NELHA lease can be negotiated with acceptable terms. Under the terms of the existing NELHA leases, we could be required to remove improvements at the end of the lease terms. Based upon our analysis, we do not believe the projected cost for such removal to be reasonably estimable, and we also believe we are unlikely to incur such costs, given historical practices. However, conditions could change in the future and it is not possible to predict such changes or estimate any impact thereof. We also rent warehouse space in Rancho Cucamonga, California.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to provide a reader of our consolidated financial statements with a narrative of our financial condition, results of operations, liquidity and certain other factors that may affect our future results from the perspective of management.

Our MD&A should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this Form 10-K. A more comprehensive description of our products and markets for such products is provided in Part I. Item 1. Business.

Overview

We are an agricultural company and a world leader in the production of natural products derived from microalgae grown in complex and intricate agricultural systems on the Kona coast of Hawaii. We have core competency in cultivating and processing microalgae into high-value, high-quality natural products for the human dietary supplement market. We are unique in that our microalgae are grown in open ponds which, similar to natural land and plant-based horticulture, require favorable weather conditions. In our case these conditions include consistent light, warm temperatures and low rainfall to achieve optimum production. Equally important is a nutrient-rich environment, which requires the proper control and balance of necessary nutrients to support growth and yields. Greater variability in these environmental factors more commonly occur in our winter growing season.

Our products are sold as consumer-packaged goods through natural products distributors, retailers and online channels, and direct to consumers, primarily in the U.S., as well as in bulk form to manufacturers, formulators and distributors worldwide in the health foods, cosmetic manufacturers and nutraceuticals and dietary supplement markets.

We will continue to focus on growing the market for our high quality, higher margin consumer products by emphasizing the higher nutritional content of our Hawaiian Spirulina Pacifica® and the multiple health benefits of our BioAstin® Hawaiian Astaxanthin®. We generated 21% and 18% of our revenues outside of the United States during the years ended March 31, 2025 and 2024, respectively. Competing in a global marketplace, we are influenced by the general economic conditions of the countries in which our customers operate, including adherence to our customers’ local governmental regulations and requirements. Since substantially all sales are made in U.S. currency, we have no material foreign exchange exposure.

Our production levels have a significant impact on our gross profit margin, as well as our ability to meet customer demand. Because our processes are agricultural and a large percentage of our production costs are fixed, it is important to maintain production volumes to support the minimal resource levels required to sustain a large-scale open culture agricultural facility. Our production costs include customary variables such as availability and costs of personnel, raw materials, energy, water and freight. These variables fluctuate based on changes in the local, national and world economies. More complex variables include cultivation methods, feeding formulations and harvesting processes, all of which include efforts to anticipate the extent of weather and environmental events and make timely and sufficient adjustments. Although the variability of such costs cannot be fully anticipated, we have focused increased effort in this area in order to produce both spirulina and astaxanthin at levels sufficient to fully absorb production costs into inventory.

Fresh water is critical for our natural astaxanthin and spirulina production, and while we have not experienced any long-term constraint on fresh-water availability, future availability could be negatively impacted by significant growth in the local population as well as by throughput constraints on the water delivery infrastructure owned by the County of Hawaii. Given the criticality of fresh water to our operations and the community, we recycle fresh water where possible and have developed additional water recycling systems in our efforts to utilize fresh water efficiently. Both fresh and sea water require electricity for pumping; and the cost of our electricity depends on the cost of fuel which is, in turn, tied to the global price of crude oil.

Complex biological processes in the cultivation and processing of our microalgae are influenced by factors beyond our control—the weather, for example. As a result, we cannot be sure that adequate production levels will be consistent period over period. To the extent that our production levels are not sufficient to absorb these costs on a period basis, we recognize abnormal and non-inventoriable production costs, including fixed cost variances from normal production capacity, as an expense in the period incurred. Abnormal amounts of freight, handling costs and wasted material (spoilage) are recognized as current-period charges and fixed production overhead costs are allocated to inventory based on the normal capacity of production facilities. Normal capacity is defined as the production expected to be achieved over a number of periods or seasons under normal circumstances, taking into account the loss of capacity resulting from planned maintenance. To offset increased production costs, we seek ways to increase production efficiencies in volume yield, potency, and quality consistent with our commitment to produce high-value, high-quality products.

We utilize several third-party contractors for the encapsulation of our gelcaps, molding of our gummies and for the packaging of our finished products. Although these services are available from a limited number of sources, we believe that we have the ability to use other parties if any of the current contractors become unavailable.

Table of Contents

During fiscal year 2025, we started seeing higher demand for our bulk products. Although we experienced a loss from operations, our higher manufacturing efficiencies and lower operating expenses resulted in a more favorable operating loss compared to the prior year by 45%.

Fiscal 2025 Summary:

	●	Net sales for the year were $24.2 million, an increase of $1.1 million, or 5.0% from the prior year, driven primarily by a $1.9 million, or 63.2%, increase in bulk sales of spirulina and astaxanthin, offset by $1.0 million, or 5.3%, decrease in packaged sales of spirulina and astaxanthin.

	●	The pretax loss for the year was $3.2 million compared to a pretax loss of $5.3 million in fiscal 2024.

	●	Cash as of March 31, 2025 decreased by $0.4 million compared to last year primarily due to the net loss for the year and an increase in inventories, partially offset by draws on the line of credit - related party.

Fiscal 2024 Summary:

	●	Net sales for the year were $23.1 million, a decrease of $0.1 million, or 0.5% from the prior year, driven primarily by a $1.0 million, or 12.0%, decrease in spirulina sales, offset by $0.9 million, or 6.3%, increase in astaxanthin sales.

	●	The pretax loss for the year was $5.3 million compared to a pretax loss of $3.4 million in fiscal 2023.

	●	Cash at March 31, 2024 decreased by $0.3 million compared to last year primarily due to the net loss for the year, an increase in accounts receivables and investments in capital expenditures, offset by draws on the line of credit - related party, proceeds from the issuance of common stock related to a private placement and a decrease in inventories as we balanced inventory with customer demand.

Fiscal 2025 results compared with Fiscal 2024

Net Sales Net sales increased $1.1 million, or 5.0%, in fiscal year ended March 31, 2025 compared with fiscal year 2024. The increase was primarily driven by a $1.1 million, or 73.9% increase in astaxanthin bulk sales and $0.8 million, or 53.0% increase in spirulina bulk sales. During fiscal year 2025, we saw higher demand in bulk sales due to both timing of customer orders and increased demand. These increases were offset by a $1.0 million, or 5.3% decrease in both astaxanthin and spirulina packaged sales, primarily due to timing of shipments.

Gross Profit Gross profit as a percent of net sales increased by 2.6 percentage points compared to fiscal year 2024, which was the result of higher production volumes, which resulted in lower production costs for the current fiscal year.

Operating Expenses Operating expenses decreased $1.2 million, or 10.9% compared to fiscal year 2024. Selling and marketing expenses decreased primarily due to lower online selling fees, advertising and commissions, as well as lower research and development costs related to lower headcount.

Income Taxes We recorded an income tax expense of $8,000 in fiscal year 2025 for state taxes, compared to income tax expense of $7,000 in fiscal 2024.

Liquidity and Going Concern

The accompanying consolidated financial statements, as of and for the fiscal years ended March 31, 2025 and 2024, have been prepared assuming we will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. We sustained operating losses and negative cash flows from operations for these same periods. Furthermore, as discussed below, we were not in compliance with two debt covenant requirements as of March 31, 2024 and 2025. In June 2023, the Bank instituted a freeze on additional advances from the Revolving Credit Agreement (the “Line of Credit”). These conditions raise substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments to the carrying amounts and classification of assets, liabilities, and reported expense that may be necessary if we were unable to continue as a going concern.

As of March 31, 2025, we had cash of $0.3 million and working capital of $0.3 million compared to $0.7 million and $2.0 million, respectively, as of March 31, 2024. We had the Line of Credit with the Bank that provided for borrowings up to $2.0 million on a revolving basis, however, as part of the covenant waiver as of March 31, 2023, the borrowings under the Line of Credit were frozen. On October 13, 2023, the Bank converted the Line of Credit to a term loan in the amount of $1.48 million with an original maturity date of August 30, 2024 (the “2023 Loan”). As of March 31, 2025 and 2024, we had $0.8 million and $1.2 million, respectively, outstanding on the 2023 Loan (see Note 5 in the notes to consolidated financial statements).

We also have a loan facility with a related party that allows us to borrow up to $4.0 million on a revolving basis (the “Revolver”). As of March 31, 2025 and 2024, we had $3.0 million and $1.25 million, respectively, of outstanding borrowings on the Revolver, which were included in line of credit – related party on the consolidated balance sheets. The Revolver expires on April 12, 2026 (see Note 5 and 15 in the notes to consolidated financial statements).

As of March 31, 2025, we had $3.0 million of debt (the "2012 Loan") payable to the Bank that requires the payment of principal and interest monthly through August 2032. Pursuant to the 2012 Loan and 2023 Loan, we are subject to annual financial covenants, customary affirmative and negative covenants and certain subjective acceleration clauses. As of March 31, 2025, our debt service coverage ratio and current ratio fell short of the Bank’s annual requirement. On June 4, 2025, the Bank provided us with a letter waiving the covenant violations as of March 31, 2025, but noting that the Bank reserves its right to declare a default in the future if any covenants remain out of compliance at applicable measurement dates. As of March 31, 2024, our debt service coverage ratio and current ratio fell short of the Bank’s annual requirement. On September 12, 2024, the Bank provided us with a letter waiving the covenant violations as of March 31, 2024.

In April 2019, we obtained a loan in the amount of $1.5 million from a related party. The proceeds were used to pay down accounts payable and for general operating capital purposes. On April 12, 2021, December 14, 2022, August 14, 2023, and August 9, 2024, we amended this loan (see Note 5 and 15 in the notes to consolidated financial statements). As of both March 31, 2025 and 2024, we had $1.0 million outstanding on the related party note. The loan matures on April 12, 2027.

We continue to experience a loss from operations and continue to rely on our funding source to provide liquidity. To address the resulting continued cash flow challenges, we continue to monitor cost savings initiatives implemented in fiscal year 2023. This includes: stopping or slowing production of inventory in alignment with current customer demand throughout the year, maintaining a reduced headcount and compensation, primarily through attrition and furloughs, respectively, and eliminating certain discretionary selling, general and administrative and research and development expenses. We have made some additional changes in the sales and marketing team by hiring a Head of Sales to strengthen our eCommerce footprint, optimize our marketing efforts and improve our retail strategy.

Funds generated by operating activities and available cash are our most significant sources of liquidity for working capital requirements, debt service and funding of maintenance levels of capital expenditures. We have developed our operating plan to produce a significant portion of the cash flows necessary to meet all financial requirements, with the remaining need for capital raising. Although we have a history of either being in compliance with debt covenants, or obtaining the necessary waivers, execution of our operating plan is dependent on many factors, some of which are not within our control. However, no assurances can be provided that we will achieve our operating plan and cash flow projections for the next fiscal years or our projected consolidated financial position as of March 31, 2026. Such estimates are subject to change based on future results and such change could cause future results to vary significantly from expected results.

As further described in the Risk Factors located in Item 1A of this Annual Report on Form 10-K, our results of operations and financial condition can be affected by numerous factors, many of which are beyond our control and could cause future results of operations to fluctuate materially as it has in the past.

Future operating results may fluctuate as a result of changes in sales volumes to our largest customers, weather patterns, increased competition, increased materials, nutrient and energy costs, government regulations and other factors beyond our control.

A significant portion of our expense levels are relatively fixed, so the timing of increases in expenses is based in large part on forecasts of future sales. If net sales are below expectations in any given period, the adverse impact on results of operations may be magnified by our inability to adjust spending quickly enough to compensate for the sales shortfall. We may also choose to reduce prices or increase spending in response to market conditions, which may have a material adverse effect on financial condition and results of operations.

Off-Balance Sheet Arrangements

As of March 31, 2025, we had no off-balance sheet arrangements or obligations.

Impact of Inflation

Inflationary factors such as increases in the costs of materials, utilities and labor directly affect our operations. We are also experiencing overall lower demand in packaged sales as consumers are feeling the impacts of higher inflation and are closely managing their discretionary expenses. The exact impact on our results is difficult to isolate and quantify given the macroeconomic environment. Most of our leases provide for cost-of-living adjustments and require us to pay for insurance and maintenance expenses, all of which are subject to inflation. Additionally, our future lease costs for new facilities may include potentially escalating costs of real estate and construction. There is no assurance that we will be able to pass on increased costs to our customers.

Depreciation expense is based on our historical cost of fixed assets and is therefore potentially less than it would be if it were based on current replacement cost. While property and equipment acquired in prior years will ultimately have to be replaced at higher prices, it is expected that replacement will be a gradual process over many years.

Cash Flows The following table summarizes our cash flows from operating, investing and financing activities for each of the past two fiscal years:

	2025			2024
	(in thousands)
Total cash is (used in) provided by:
Operating activities	$	(1,193	)	$	(455	)
Investing activities		(247	)		(381	)
Financing activities		990			569

Decrease in cash	$	(450	)	$	(267	)

Cash used in operating activities in fiscal 2025 was primarily the result of a net loss of $3.2 million and an increase of $0.5 million in inventories, offset partially by non-cash charges of $2.2 million.

Cash used in operating activities in fiscal 2024 was primarily the result of a net loss of $5.3 million and an increase of $0.8 million in accounts receivable, offset partially by non-cash charges of $2.4 million and a decrease of $3.4 million in inventories.

Cash used in investing activities in fiscal years 2025 and 2024 includes costs for acquiring equipment and leasehold improvements at our Kona facility.

Cash provided by financing activities in fiscal 2025 consisted primarily of additional draws on the related party line of credit of $1.8 million, partially offset by the paydown of $0.5 million on the 2023 Loan and $0.3 million of debt service payments.

Cash provided by financing activities in fiscal 2024 consisted primarily of the proceeds from the Private Placement of $0.4 and draws on the related party line of credit of $0.8 million, offset by debt service payments of $0.2 million and paydown of the Bank line of credit of $0.3 million.

Recent Accounting Pronouncements

Except as discussed in Note 2, Significant Accounting Policies, in the notes to our consolidated financial statements included in this Annual Report on Form 10-K, we have considered all new accounting pronouncements and have concluded that there are no new pronouncements that may have a material impact on our results of operations, financial condition, or cash flows, based on current information.

Application of Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of financial statements in conformity with those accounting principles requires management to make judgments and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Management regularly re-evaluates its judgments and estimates which are based upon historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Management believes that of its significant accounting policies, policies that may involve a higher degree of judgment and complexity are inventory valuations, valuation of equipment and leasehold improvements and long-lived assets, and income taxes.

Table of Contents

Revenue - We record revenue based on the five-step model which includes: (1) identifying the contract with the customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations; and (5) recognizing revenue when the performance obligations are satisfied. Substantially all of our revenue is generated by fulfilling orders for the purchase of our microalgal dietary supplements to retailers, wholesalers, or direct to consumers via online channels, with each order considered to be a distinct performance obligation. These orders may be formal purchase orders, verbal phone orders, e-mail orders or orders received online. Shipping and handling activities for which we are responsible under the terms and conditions of the order are not accounted for as performance obligations but as fulfillment costs. These activities are required to fulfill our promise to transfer the goods and are expensed when revenue is recognized.

Revenue is measured as the net amount of consideration expected to be received in exchange for fulfilling a performance obligation. We have elected to exclude sales, use and similar taxes from the measurement of the transaction price. The amount of consideration expected to be received and revenue recognized includes estimates of variable consideration, which includes costs for trade promotion programs, coupons, returns and early payment discounts. Such estimates are calculated using historical averages adjusted for any expected changes due to current business conditions and experience. We review and update these estimates at the end of each reporting period and the impact of any adjustments are recognized in the period the adjustments are identified. In assessing whether collection of consideration from a customer is probable, we consider the customer's ability and intent to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, typically 30 days from the invoice date, which occurs on the date of transfer of control of the products to the customer. Revenue is recognized at the point in time that control of the ordered products is transferred to the customer. Generally, this occurs when the product is delivered, or in some cases, picked up from one of our distribution centers by the customer. Revenue from extraction services is recognized when control is transferred upon completion of the extraction process.

Customer contract liabilities consist of customer deposits received in advance of fulfilling an order and are shown separately on the consolidated balance sheets. During the years ended March 31, 2025 and 2024, we recognized $45,000 and $26,000, respectively, of revenue from deposits that were included in contract liabilities as of March 31, 2024 and 2023, respectively. Our contracts have a duration of one year or less and therefore, we have elected the practical expedient of not disclosing revenues allocated to partially unsatisfied performance obligations.

Inventories - We record inventories at the lower of cost or net realizable value. Cost is defined as the sum of the applicable expenditures and charges directly or indirectly incurred in bringing inventories to their existing condition and location. Our inventories are valued using the first-in, first-out method. Inventory values are subject to many critical estimates, including production levels and capacity, changes in the prices paid for raw materials, supplies, and labor, changes in yield, potency, and quality of biomass, changes in processing or production methods, and changes in the carrying value of our inventories resulting from the prices our customers are willing to pay for our products. Such estimates are revised quarterly. Changes in management’s estimates could result in increases or decreases in the recorded amounts of inventory and cost of sales.

To the extent that our production levels are not sufficient to absorb all production costs on a period basis, we recognize abnormal production costs, including fixed cost variances from normal production capacity, fixed production overhead costs, idle facilities, freight handling costs and spoilage, as an expense in the period incurred, without adjusting overhead absorption rates. Normal capacity is defined as the production expected to be achieved over a number of periods or seasons under normal circumstances, taking into account the loss of capacity resulting from planned maintenance. Changes in management’s estimates could result in increases or decreases in the recorded amounts of inventory and cost of sales.

Beginning in fiscal 2021 through fiscal year 2023, cultivation of astaxanthin was completed in the first six months of the fiscal year during the most productive months of the year due to the best growing conditions, compared to year-round cultivation in the prior fiscal years. In fiscal year 2024, cultivation of astaxanthin reverted back to year-round in order to manage staffing constraints, however, in fiscal year 2025, cultivation of astaxanthin was completed in the most productive nine months of the year. We calculate total production costs for the year based on normal capacity of production expected to be achieved in a year under normal circumstances. These costs are then allocated into inventory based on the period of production, not including abnormal production costs. Allocating fixed and overhead costs requires management’s judgement to determine when production is outside of the normal range of expected variation in production.

Management reviews inventory levels, inventory turnover, product age and product marketability quarterly to evaluate recoverability and determine if a write-off of inventory is deemed necessary.

Equipment and leasehold improvements - Equipment and leasehold improvements are reported at cost less accumulated depreciation and amortization. Self-constructed leasehold improvements include design, construction and supervision costs. These costs are recorded in construction in progress and are transferred to equipment and leasehold improvements when construction is completed, and the facilities are placed in service. Long-lived assets, such as property and equipment and purchased intangibles subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized to the extent that the carrying amount exceeds the asset’s fair value. We recognized $5,000 impairment of long-lived assets as of March 31, 2025, but did not recognize any impairment of long-lived assets as of March 31, 2024.

Stock-Based Compensation - We provide compensation benefits in the form of stock options, restricted stock units (“RSUs”) and restricted stock grants to employees and non-employee directors. Our stock-based compensation expense is based on the fair value of awards, adjusted for estimated forfeitures, and amortized on a straight-line basis over the requisite service period for stock options and RSUs. The fair value of stock options is estimated as of the date of grant using the Black-Scholes option pricing model. This model requires input assumptions for our expected dividend yield, expected stock price volatility, risk-free interest rate and the expected option term. Restricted stock and RSUs are valued at the fair value of our common stock as of the date of the grant. See Note 9 in the notes to our consolidated financial statements.

Income taxes - Income taxes are accounted for under the asset and liability method. The asset and liability method require the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using income tax rates applicable to the period in which the tax difference is expected to reverse.

Our judgment is required in determining any valuation allowance recorded against deferred tax assets, specifically net operating loss carryforwards, tax credit carryforwards and deductible temporary differences that may reduce taxable income in future periods. In assessing the need for a valuation allowance, we consider all available evidence including past operating results, estimates of future taxable income and tax planning opportunities. In the event we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to income tax expense in the period in which such determination is made.

Cyanotech Corporation

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Cyanotech Corporation (a Nevada corporation) and its subsidiary (the “Company”) as of March 31, 2025, and the related consolidated statements of operations, stockholders’ equity, and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2025, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and negative cash flows from operations, including for the fiscal year ended March 31, 2025. Further, the Company was not in compliance with two debt covenant requirements as of March 31, 2025. These conditions, along with other matters as set forth in Note 1, raise substantial doubt about the Company's ability to continue as a going concern. Management's plan in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

CYANOTECH CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.	ORGANIZATION AND BASIS OF PRESENTATION

Cyanotech Corporation (the “Company”), located in Kailua-Kona, Hawaii, was incorporated in the state of Nevada on March 3, 1983 and is traded on the OTCQB Market under the symbol “CYAN”. The Company is engaged in the production of natural products derived from microalgae for the dietary supplements market.

The Company is an agricultural company that produces high value natural products derived from microalgae grown in complex and intricate open-pond agricultural systems on the Kona coast of Hawaii. The Company's products include Hawaiian Spirulina Pacifica®, a superfood with numerous benefits, including boosting the immune system and overall cellular health; and BioAstin® Hawaiian Astaxanthin®, a powerful antioxidant shown to support and maintain the body's natural inflammatory response.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of Cyanotech Corporation and its wholly owned subsidiary, Nutrex Hawaii, Inc. (“Nutrex Hawaii” or “Nutrex”). The Company operates in one business segment and uses one measurement of profitability for its business. Intercompany balances and transactions have been eliminated in consolidation.

Liquidity and Going Concern

The accompanying consolidated financial statements, as of and for the fiscal years ended March 31, 2025 and 2024, have been prepared assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company sustained operating losses and negative cash flows from operations for these same periods. Furthermore, as discussed below, the Company was not in compliance with two debt covenant requirements as of March 31, 2025 and 2024. In June 2023, First Foundation Bank (the “Bank”) instituted a freeze on additional advances from the Revolving Credit Agreement (the “Line of Credit”). These conditions raise substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements do not include any adjustments to the carrying amounts and classification of assets, liabilities, and reported expense that may be necessary if the Company was unable to continue as a going concern.

As of March 31, 2025, the Company had cash of $257,000 and working capital of $302,000 compared to $707,000 and $2,037,000, respectively, as of March 31, 2024. The Company had the Line of Credit with the Bank that provided for borrowings up to $2,000,000 on a revolving basis, however, as part of the covenant waiver as of March 31, 2023, the borrowings under the Line of Credit were frozen. On October 13, 2023, the Bank converted the Line of Credit to a term loan in the amount of $1,480,000 with an original maturity date of August 30, 2024 (the “2023 Loan”). As of March 31, 2025 and 2024, the Company had $760,000 and $1,240,000 outstanding on the 2023 Loan, with a maturity date extended to March 31, 2026 (See Note 5).

The Company also has a loan facility with a related party that allows the Company to borrow up to $4,000,000 on a revolving basis (the “Revolver”). As of March 31, 2025 and March 31, 2024, the Company had $3,000,000 and $1,250,000, respectively, of outstanding borrowings on the Revolver, which were included in line of credit – related party on the consolidated balance sheets. The Revolver expires on April 12, 2026 (see Notes 5 and 15).

As of March 31, 2025, the Company had $2,954,000 of debt (“2012 Loan”) payable to the Bank that requires the payment of principal and interest monthly through August 2032. Pursuant to the 2012 Loan and 2023 Loan, the Company is subject to annual financial covenants, customary affirmative and negative covenants and certain subjective acceleration clauses. As of March 31, 2025, the Company’s debt service coverage ratio and current ratio fell short of the Bank’s annual requirement. On June 4, 2025, the Bank provided the Company with a letter waiving the covenant violations as of March 31, 2025, but noting that the Bank reserves its right to declare a default in the future if any covenants remain out of compliance at applicable measurement dates. As of March 31, 2024, the Company’s debt service coverage ratio and current ratio fell short of the Bank’s annual requirement. On September 12, 2024, the Bank provided the Company with a letter waiving the covenant violations as of March 31, 2024.

In April 2019, the Company obtained a loan in the amount of $1,500,000 from a related party. The proceeds were used to pay down accounts payable and for general operating capital purposes. On April 12, 2021, December 14, 2022, August 14, 2023, and August 9, 2024, the Company amended this loan (see Notes 5 and 15). As of both March 31, 2025 and 2024, the Company had $1,000,000 outstanding on the related party note. The loan matures on April 12, 2027.

The Company continues to experience a loss from operations and continues to rely on its funding source to provide liquidity. To address the resulting continued cash flow challenges, the Company continues to monitor cost savings initiatives implemented in fiscal year 2023. This includes: stopping or slowing production of inventory in alignment with current customer demand throughout the year, maintaining a reduced headcount and compensation, primarily through attrition and furloughs, respectively, and eliminating certain discretionary selling, general and administrative and research and development expenses. The Company has made some additional changes in the sales and marketing team by hiring a Head of Sales to strengthen its eCommerce footprint, optimize the Company’s marketing efforts and improve its retail strategy.

Table of Contents

Funds generated by operating activities and available cash are the Company's most significant sources of liquidity for working capital requirements, debt service and funding of maintenance levels of capital expenditures. The Company has developed its operating plan to produce a significant portion of the cash flows necessary to meet all financial requirements, with the remaining need for capital raising. Although the Company has a history of either being in compliance with debt covenants, or obtaining the necessary waivers, execution of its operating plan is dependent on many factors, some of which are not within the control of the Company. However, no assurances can be provided that the Company will achieve its operating plan and cash flow projections for the next fiscal year or its projected consolidated financial position as of March 31, 2026. Such estimates are subject to change based on future results and such change could cause future results to vary significantly from expected results.

2.	SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of any contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the periods reported. Management reviews these estimates and assumptions periodically and reflects the effect of revisions in the period that they are determined to be necessary. Actual results could differ from those estimates and assumptions.

Financial Instruments and Fair Value

The Company applies a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described below:

	Level 1 —	Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.
	Level 2 —	Inputs to the valuation methodology include:

	●	Quoted prices for similar assets or liabilities in active markets;
	●	Quoted prices for identical or similar assets or liabilities in inactive markets;
	●	Inputs other than quoted prices that are observable for the asset or liability; and
	●	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified contractual term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 —

Inputs to the valuation methodology are unobservable and significant to the fair value.

There were no financial assets or liabilities measured at fair value on a recurring basis as of March 31, 2025 and 2024.

Accounts Receivable, Accounts Payable, Accrued Expenses and Customer Deposits - Due to the short-term nature of these instruments, management believes that the carrying amounts approximate fair value.

Line of Credit, Revolver, Short-Term and Long-Term Debt - The carrying amount of the Line of Credit, Revolver and short and long-term debt approximates fair value as interest rates applied to the underlying debt are adjusted quarterly to market interest rates, which approximate current interest rates for similar debt instruments of comparable maturities.

Cash

Cash primarily consists of cash on hand and cash in bank deposits.

Table of Contents

Concentration Risk

The Company maintains its cash accounts in banks located in Hawaii, which are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per bank. The Company did not have a cash bank balances as of March 31, 2025 that exceeded the balance insured by the FDIC. The Company had cash bank balances as of March 31, 2024 that exceeded the balance insured by the FDIC by $166,000. A significant portion of revenues and accounts receivables are derived from a few major customers. For the fiscal year ended March 31, 2025, two customers individually accounted for 31% and 10% of the Company’s total net sales and for the fiscal year ended March 31, 2024, two customers individually accounted for 34% and 17% of the Company’s total net sales. Two customers accounted for 61% and 72% of the Company’s accounts receivable balance as of March 31, 2025 and 2024, respectively.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not accrue interest. Credit is extended based on evaluation of the customer's financial condition. Collateral is not required. The allowance for credit losses reflects management’s best estimate of expected credit losses inherent in the accounts receivable balance. Management determines the allowance based on historical experience, specifically identified nonpaying accounts and other currently available evidence. Management reviews its customer account balances monthly with a focus on significant individual past due balances over 90 days. All other balances are reviewed on a pooled basis. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance sheet credit exposure related to its customers or otherwise.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (“FIFO”) method. Net realizable value is defined as estimated sales price less cost to dispose. Inventory costs include materials, labor, overhead and third-party costs. Management reviews and writes down inventory for known or expected inventory obsolescence based on product age and quality which may affect salability.

The Company recognizes abnormal production costs, including fixed cost variances from normal production capacity, fixed production overhead costs, idle facilities, freight handling costs and spoilage, as an expense in the period incurred, without adjusting overhead absorption rates. Normal production capacity is defined as the production expected to be achieved over a number of periods or seasons under normal circumstances, taking into account the loss of capacity resulting from planned maintenance.

Equipment and Leasehold Improvements

Equipment and leasehold improvements are stated at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives for equipment and furniture and fixtures, and the shorter of the land lease term (see Notes 4 and 7) or estimated useful lives for leasehold improvements as follows (in years):

Equipment	3	to	10
Furniture and fixtures	3	to	7
Leasehold improvements	10	to	25

Capital project costs are accumulated in construction-in-progress until completed, at which time the costs are transferred to the relevant asset and commence depreciation. Repairs and maintenance costs are expensed in the period incurred. Repairs and maintenance that significantly increase the useful life or value of the asset are capitalized and depreciated over the remaining life of the asset. The Company capitalizes interest cost incurred on funds used to construct property and equipment. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life.

Impairment of Long-Lived Assets

Management reviews long-lived assets, such as equipment, leasehold improvements and purchased intangibles subject to amortization for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized to the extent that the carrying amount exceeds the asset’s fair value. Assets to be disposed of and related liabilities would be separately presented in the consolidated balance sheet. Assets to be disposed of would be reported at the lower of the carrying value or fair value less costs to sell and would not be depreciated.

Accounting for Asset Retirement Obligations

Management evaluates on a quarterly basis the potential liability for asset retirement obligations under the Company’s lease for its principal facility and corporate headquarters. No liability has been recognized as of March 31, 2025 and 2024 (see Note 7).

Revenue Recognition

The Company records revenue based on the five-step model which includes: (1) identifying the contract with the customer; (2) identifying the performance obligations in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligations; and (5) recognizing revenue when the performance obligations are satisfied. Substantially all of the Company’s revenue is generated by fulfilling orders for the purchase of its microalgal dietary supplements to retailers, wholesalers, or direct to consumers via online channels, with each order considered to be a distinct performance obligation. These orders may be formal purchase orders, verbal phone orders, e-mail orders or orders received online. Shipping and handling activities for which the Company is responsible under the terms and conditions of the order are not accounted for as performance obligations but as fulfillment costs. These activities are required to fulfill the Company’s promise to transfer the goods and are expensed when revenue is recognized.

Revenue is measured as the net amount of consideration expected to be received in exchange for fulfilling a performance obligation. The Company has elected to exclude sales, use and similar taxes from the measurement of the transaction price. The amount of consideration expected to be received, and revenue recognized includes estimates of variable consideration, which includes costs for trade promotion programs, coupons, returns and early payment discounts. Such estimates are calculated using historical averages adjusted for any expected changes due to current business conditions and experience. The Company reviews and updates these estimates at the end of each reporting period and the impact of any adjustments are recognized in the period the adjustments are identified. In assessing whether collection of consideration from a customer is probable, the Company considers the customer's ability and intent to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, typically 30 days from the invoice date, which occurs on the date of transfer of control of the products to the customer. Revenue is recognized at the point in time that control of the ordered products is transferred to the customer. Generally, this occurs when the product is delivered, or in some cases, picked up from one of the Company’s distribution centers by the customer. Revenue from extraction services is recognized when control is transferred upon completion of the extraction process.

Customer contract liabilities consist of customer deposits received in advance of fulfilling an order and are shown separately on the consolidated balance sheets. During the years ended March 31, 2025 and 2024, the Company recognized $45,000 and $26,000, respectively, of revenue from deposits that were included in contract liabilities as of March 31, 2024 and 2023, respectively. The Company’s contracts have a duration of one year or less and therefore, the Company has elected the practical expedient of not disclosing revenues allocated to partially unsatisfied performance obligations.

Research and Development

Research and development costs are expensed as incurred and consist primarily of labor, benefits and outside research.

Advertising

Advertising costs are expensed as incurred. Total advertising expense for the years ended March 31, 2025 and 2024 was $1,123,000 and $1,308,000, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. The asset and liability method require the recognition of deferred tax assets and liabilities for the expected future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using income tax rates applicable to the period in which the tax difference is expected to reverse.

Judgment is required in determining any valuation allowance recorded against deferred tax assets, specifically net operating loss carryforwards, tax credit carryforwards and deductible temporary differences that may reduce taxable income in future periods. In assessing the need for a valuation allowance, the Company considers all available evidence including past operating results, estimates of future taxable income and tax planning opportunities. In the event the Company changes its determination as to the amount of deferred tax assets that can be realized, it will adjust its valuation allowance with a corresponding impact to income tax expense in the period in which such determination is made.

In evaluating a tax position for recognition, management evaluates whether it is more likely than not that a position will be sustained upon examination, including resolution of related appeals or litigation processes, based on the technical merits of the position. If the tax position meets the more likely than not recognition threshold, the tax position is measured and recognized in the Company’s consolidated financial statements as the largest amount of tax benefit that, in management’s judgment, is greater than 50% likely of being realized upon settlement. As of March 31, 2025 and 2024, there were no liabilities for income tax associated with unrecognized tax benefits.

Table of Contents

The Company recognizes accrued interest related to unrecognized tax benefits as well as any related penalties in interest expense in its consolidated statements of operations. During the fiscal years ended March 31, 2025 and 2024, there were no accruals for the payment of interest and penalties related to uncertain tax positions.

Share-Based Compensation

The Company accounts for share-based payment arrangements using fair value. The Company currently has no liability-classified awards. Equity-classified awards, including grants of restricted stock, restricted stock units and employee stock options, are measured at the grant-date fair value of the award and are not subsequently remeasured unless an award is modified. The cost of equity-classified awards is recognized in the consolidated statements of operations over the period during which an employee is required to provide the service in exchange for the award, or the vesting period. All stock-based compensation for restricted stock, restricted stock units and stock options has been classified as general and administrative expense in the consolidated statements of operations.

The Company utilizes the Black-Scholes option pricing model to determine the fair value of each option award. Expected volatilities are based on the historical volatility of the Company’s common stock over a period consistent with that of the expected term of the options. The expected term of the options is estimated based on factors such as vesting periods, contractual expiration dates and historical exercise behavior. The risk-free rates for periods within the contractual life of the options are based on the yields of U.S. Treasury instruments with terms comparable to the estimated option terms. The forfeiture rate of the options is estimated at the time of the grant and is based on historical forfeitures of similar grants. The fair value of restricted stock units is the closing stock price on the grant date.

Per Share Amounts

Basic earnings (loss) per common share is calculated by dividing net income (loss) for the year by the weighted average number of common shares outstanding during the year. Diluted earnings per common share is calculated by dividing net income for the year by the sum of the weighted average number of common shares outstanding during the year plus the number of potentially dilutive common shares (“dilutive securities”) that were outstanding during the year. Dilutive securities include restricted stock units and stock options granted pursuant to the Company’s stock option plans. Dilutive securities related to the Company’s stock option plans are included in the calculation of diluted earnings per common share using the treasury stock method. Potentially dilutive securities are excluded from the computation of earnings per share in periods in which a net loss is reported, as their effect would be antidilutive. A reconciliation of the numerators and denominators of the basic and diluted income (loss) per common share calculations for the fiscal years ended March 31, 2025 and 2024 is presented in Note 11.

Recent Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses” (“Topic 326”), which was subsequently amended in November 2018 through ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses” (“CECL”). CECL requires entities to estimate lifetime expected credit losses for trade and other receivables, net investment in leases, financing receivables, debt securities and other instruments, which will result in earlier recognition of credit losses. The guidance is effective for interim and annual periods beginning after December 15, 2022. The Company adopted this standard as of April 1, 2023, however, due to the relatively short-term nature of its accounts receivable and history of limited bad debt expense, the impact of this guidance was not significant to the Company’s consolidated financial statements and related disclosure. The Company will continue to evaluate the impact of CECL going forward.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires disclosure of incremental segment information on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and it requires retrospective application to all prior periods presented in the financial statements. The Company retrospectively adopted this new standard effective March 31, 2025. The adoption of ASU 2023-07 did not change the way that the Company identifies its reportable segment and, as a result, did not have a material impact on the Company’s segment related disclosure. See Note 13 for further information on the Company’s reportable segment.

Table of Contents

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosure” (“ASU 2023-09”), which enhances the transparency and decision usefulness of income tax disclosures. Adjustments to the annual disclosure of income taxes include: a tabulate rate reconciliation comprised of eight specific categories; income taxes paid, disaggregated between significant federal, state, and foreign jurisdictions; eliminating requirements to disclose the nature and estimate of reasonably possible changes to unrecognized tax benefits in the next 12 months or that an estimated range cannot be made; and adds a requirement to disclose income (or loss) from continuing operations before income tax expense (or benefit) and income tax expense (or benefit) from continuing operations disaggregated between domestic and foreign. ASU 2023-09 is effective for public business entities for fiscal years beginning on or after December 15, 2024, with early adoption permitted. The amendments in ASU 2023-09 should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating ASU 2023-09 to determine its impact on the Company’s disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement–Reporting Comprehensive Income–Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which enhances the disclosure of expenses on the income statement. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating ASU 2024-03 to determine its impact on the Company’s disclosures.

3.	INVENTORIES

Inventories consist of the following as of March 31, 2025 and 2024:

	2025		2024
	(in thousands)
Raw materials	$	567	$	1,149

Inventories	$	7,788	$	7,313

The Company had abnormal production capitalization of $112,000 for the fiscal year ended March 31, 2025 and abnormal production expense of $206,000 to cost of sales for the fiscal year ended March 31, 2024. The capitalization in fiscal year 2025 was primarily due to increased demand for bulk spirulina, which drove increased production volumes.

In fiscal year 2024, cultivation of astaxanthin was completed year-round in order to manage staffing constraints, however, in fiscal year 2025, cultivation of astaxanthin was completed in the most productive nine months of the year. The Company calculates total production costs for the year based on normal capacity of production expected to be achieved in a year under normal circumstances. These costs are then allocated into inventory based on the period of production, not including abnormal production costs. Allocating fixed and overhead costs requires management’s judgement to determine when production is outside of the normal range of expected variation in production.

Other non-inventoriable fixed costs of $90,000 and $467,000 were expensed to cost of sales for the fiscal years ended March 31, 2025 and 2024, respectively. In fiscal year 2024, these fixed costs were primarily due to lower overall production volumes with higher than normal excess capacity expense for the full year compared to the prior fiscal year.

Net realizable value adjustments for spirulina products of $22,000 and $256,000 were expensed to cost of sales for the fiscal year ended March 31, 2025 and 2024, respectively. In fiscal year 2024, this adjustment was primarily due to low production volumes with high fixed cost base.

Line of Credit and Term Loans

On June 3, 2016, the Company entered into a Credit Agreement with the Bank after the necessary approvals from the State of Hawaii were received, to secure the lien on the Company’s leasehold property in Kona, Hawaii. The Credit Agreement further defined the terms and conditions for the 2012 Loan and allowed for the Line of Credit, which was subsequently converted to the 2023 Loan. The Credit Agreement grants the Bank the following security interests in the Company’s property: (a) a lien on the Company’s leasehold interest in its Kona facility; (b) an assignment of the Company’s interest in leases and rents on its Kona facility; and (c) a security interest in all fixtures, furnishings and equipment related to or used by the Company at the Kona facility. Each security interest is further subject to the terms of the Credit Agreement.

On October 13, 2023, the Bank converted the Line of Credit to the 2023 Loan in the amount of $1,480,000, with no further advances or disbursements under this facility, with an original maturity of August 30, 2024. On August 28, 2024, the Bank extended the maturity date of the 2023 Loan from August 30, 2024 to March 31, 2025. On June 2, 2025, the Bank extended the maturity date of the 2023 Loan from March 31, 2025 to March 31, 2026, at which time the full unpaid principal balance owed under the Credit Agreement, together with all interest, shall be due and payable in full. The 2023 Loan was amended to require four equal installments due May 2025 through August 2025 of $77,500 plus interest accrued, then beginning in September 2025, monthly payments of $40,000 plus interest accrued. All interest on the unpaid balance of the loan is accrued at the Wall Street Journal prime rate plus 2%, floating, provided that at no time shall the annual interest rate be less than 7.0%. As of March 31, 2025 and 2024, the Company had $760,000 and $1,240,000, respectively, outstanding on the 2023 Loan which bears interest at 7.5% and 8.5%, respectively, plus 2%. The 2023 Loan was included in current liabilities on the consolidated balance sheets.

In 2012, the Company executed the 2012 Loan with the Bank providing for $5,500,000 in aggregate borrowings secured by substantially all the Company’s assets, including a mortgage on the Company's interest in its lease at the National Energy Laboratory of Hawaii Authority, pursuant to a Term Loan Agreement dated August 14, 2012 (the “2012 Loan Agreement”). The 2012 Loan is evidenced by promissory notes in the amounts of $2,250,000 and $3,250,000, the repayment of which is partially guaranteed under the provisions of a United States Department of Agriculture (“USDA”) Rural Development Guarantee program. The proceeds of the 2012 Loan were used to acquire processing equipment and leasehold improvements at its Kona, Hawaii facility.

Table of Contents

The provisions of the 2012 Loan required the payment of interest only for the first 12 months of the term; thereafter, and until its maturity on August 14, 2032, the obligation fully amortizes over nineteen (19) years. Interest on the 2012 Loan accrues on the outstanding principal balance at an annual variable rate equal to the published Wall Street Journal prime rate (7.5% and 8.5% at March 31, 2025 and 2024, respectively) plus 1.0% and is adjustable on the first day of each calendar quarter and fixed for that quarter, provided that at no time shall the annual interest rate be less than 5.5%. The balance under the 2012 Loan was $2,954,000 and $3,220,000 at March 31, 2025 and 2024, respectively, and was included in current maturities of long-term debt in the debt table above. See Loan Covenants, Violations and Waiver below.

The 2012 Loan included a one-time origination and guaranty fees totaling $214,500 and an annual renewal fee payable in the amount of 0.25% of the USDA guaranteed portion of the outstanding principal balance as of December 31 of each year, beginning December 31, 2012. The USDA guaranteed 80% of all amounts owing under the 2012 Loan. The balance in unamortized debt issuance costs was $68,000 and $80,000 at March 31, 2025 and 2024, respectively, and was included in current maturities of long-term debt in the debt table above. See Loan Covenants, Violations and Waiver below.

Loan Covenants, Violations and Waiver

The Company’s 2023 Loan and 2012 Loan are subject to annual debt service and other financial covenants, including covenants which require the Company to meet key financial ratios and customary affirmative and negative covenants. As of March 31, 2023, the Company was not in compliance with the required debt service coverage ratio, however, was in compliance with the two other covenants. Due to this violation, the Bank would be contractually entitled to require immediate repayment of the outstanding term loans and the outstanding line of credit balance. On June 22, 2023, the Bank issued the Company a letter waiving the covenant violation as of March 31, 2023, and implemented an immediate freeze on any and all further advances of the Credit Agreement through the maturity date. As of March 31, 2024, the Company was not incompliance with the debt service coverage and current ratio, however, was in compliance with the third covenant. On September 12, 2024, the Bank issued a letter waiving the covenant violations as of March 31, 2024, but noting that the Bank reserves its right to declare a default in the future, if any covenants remain out of compliance at applicable measurement dates. As of March 31, 2025, the Company was not in compliance with the debt service coverage and current ratio, however, was in compliance with the third covenant. On June 4, 2025, the Bank issued a letter waiving the covenant violations as of March 31, 2025, but there can be no assurance that the Bank will provide such a waiver and may declare a default if any covenants remain out of compliance at applicable measurement dates.

Although the 2012 Loan matures in August 2032, it is probable that a debt covenant violation occurs within the next twelve months. Therefore, the 2012 Loan and related unamortized debt issuance costs are classified as current on the consolidated balance sheets as of March 31, 2025 and 2024.

Line of Credit and Debt – Related Party

In April 2019, the Company obtained a loan pursuant to the Skywords Note (as defined below in Note 15 Related Party Transactions) in the amount of $1,500,000 with a related party and the interest was payable quarterly. The Skywords Note was originally due in April 2021. In April 2021, the Company amended the Skywords Note, which extended the maturity date to April 2024, converted $500,000 into the Revolver, adjusted the interest rate to reflect a floor of 5%, and granted a security interest in substantially all of the Company’s personal property assets, subject to limited exceptions. Concurrently, with the amendment and conversion of the original Skywords Note, the Company repaid in cash the principal amount of $500,000 plus accrued interest to date of $1,900 (see Note 15). In December 2022, the Company further amended the Skywords Note to extend the maturity date to April 2025 and increase the Revolver to $1,000,000. On August 14, 2023, the Company further amended the Skywords Note to increase the Revolver to $2,000,000. On August 9, 2024, the Company further amended the Skywords Note to increase the Revolver from $2,000,000 to $4,000,000 and extend the maturity date to April 2026, as well as to extend the maturity date of the Skywords Note to April 12, 2027.

The balance under the Skywords Note was $1,000,000 at both March 31, 2025 and 2024, which was included in long-term debt in the debt table above. At March 31, 2025 and 2024, the balance under the Revolver was $3,000,000 and $1,250,000, respectively, which was included in line of credit – related party in the debt table above. Interest accrues on the outstanding principal balance and the Revolver at an annual variable rate equal to the published Wall Street Journal prime rate (7.5% and 8.5% at March 31, 2025 and 2024, respectively) plus 1.0% and is adjustable on the first day of each calendar quarter and fixed for that quarter, provided that at no time shall the annual interest rate be less than 5.0%.

7.	OPERATING LEASES

The Company’s principal facility and its corporate headquarters are located at the Natural Energy Laboratory of Hawaii Authority (“NELHA”) at Keahole Point in Kailua-Kona, Hawaii. The Company leases two properties from the State of Hawaii under a 40-year commercial lease expiring in 2035 and a 19-year commercial lease expiring in 2037. Under the terms of the existing NELHA leases, the Company could be required to remove improvements at the end of the lease terms. Under GAAP, an entity should recognize the fair value of a liability for an asset retirement obligation in the period in which the retirement obligation is incurred, if a reasonable estimate of fair value can be made. If such an estimate cannot be made in the period the asset retirement obligation is incurred, the liability should be recognized when the fair value can be reasonably estimated. Based on communications with NELHA, management does not believe the projected cost for such removal to be material to the consolidated financial statements, or likely, given historical practices. However, conditions could change in the future. It is not possible to predict such changes or estimate any impact thereof.

The Company leases facilities, equipment and land under non-cancelable operating leases expiring through 2037. One of its facility leases contains price escalations and a renewal option for five years. The NELHA land lease provides for contingent rentals in excess of minimum rental commitments based on a percentage of the Company’s sales. For fiscal years ended March 31, 2025 and 2024, there were no contingent rental payments.

Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Right-of-use assets and liabilities are based on the present value of lease payments over the lease terms, using the Company’s incremental borrowing rate based on the information available at recognition, and the Company has elected to exclude non-lease components. The Company also leases two 84-month solar leases for two of its buildings and a 48-month lease for equipment, which are included in the right-of-use assets and liabilities. As of March 31, 2025, the weighted average remaining lease terms of all operating leases was 8.6 years, the weighted average discount rate was 7.4% and the operating lease costs were $840,000. As of March 31, 2024, the weighted average remaining lease terms of all operating leases was 9.1 years, the weighted average discount rate was 7.3% and the operating lease costs were $818,000. For the fiscal year ended March 31, 2025, non-cash right-of-use assets obtained in exchange for operating lease obligations was $18,000, representing the lease renewal of one of the Company's equipment leases. There were no new leases for the fiscal year ended March 31, 2024.

8.	OTHER COMMITMENTS AND CONTINGENCIES

From time to time, the Company may be involved in litigation and investigations relating to claims and matters arising out of its operations in the normal course of business. There were no significant legal matters outstanding at March 31, 2025.

As of March 31, 2025 and 2024, the Company had purchase obligations of $1,215,000 and $808,000, respectively, including agreements to purchase goods or services that are enforceable, are legally binding and specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. The term of the minimum purchase agreement is for ten years, expiring in June 2034 and purchase obligations do not include agreements that are cancelable without penalty.

9.	SHARE-BASED COMPENSATION

As of March 31, 2025, the Company had two equity-based compensation plans: the 2016 Equity Incentive Plan (the “2016 Plan”) and the 2024 Independent Director Stock Option and Restricted Stock Grant Plan (the “2024 Directors Plan”). These plans allow the Company to award stock options, restricted stock units and shares of restricted common stock to eligible employees, certain outside consultants and independent directors. The Company has also issued stock options, which remain outstanding as of March 31, 2025, under the 2014 Independent Director Stock Option and Restricted Stock Grant Plan and Amendment (the “2014 Directors Plan”), an equity-based compensation plan which expired in accordance with its terms on August 22, 2024. This plan allowed the Company to award stock options and shares of restricted common stock to independent directors.

On August 25, 2016, the Company’s shareholders approved the 2016 Plan, authorizing the Board of Directors to provide incentive to the Company’s officers, employees and certain independent consultants through equity-based compensation in the form of stock options, restricted stock, restricted stock units, stock appreciation rights and other stock-based awards (together, “Stock Awards”) and performance shares and performance units (together, “Performance Awards”). Awards under the 2016 Plan are limited to the authorized amount of 1,300,000 shares, up to 600,000 of which are available for issuance in connection with Performance Awards and Stock Awards. As of March 31, 2025, there were 632,905 shares available for grant under the 2016 Plan.

Stock Options

All stock option grants made under the equity-based compensation plans were issued at exercise prices no less than the Company’s closing stock price on the date of grant. Stock options under the 2016 Plan, 2024 Directors Plan and 2014 Directors Plan (together, the “Stock Plans”) were determined by the Board of Directors or the Compensation Committee of the Board of Directors in accordance with the provisions of the respective plans. The terms of each stock option grant include vesting, exercise, and other conditions are set forth in a Stock Option Agreement evidencing each grant. No stock option can have a life in excess of ten (10) years. The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option pricing model. The model requires various assumptions, including a risk-free interest rate, the expected term of the stock options, the expected stock price volatility over the expected term of the stock options, and the expected dividend yield. Compensation expense for employee stock options is recognized ratably over the vesting term. Compensation expense recognized for options issued under the Stock Plans was $54,000 and $98,000 for the fiscal years ended March 31, 2025 and 2024, respectively.

Restricted Stock Units

RSUs are service-based awards granted to eligible employees under our 2016 Plan. RSUs represents a right to one share of the Company’s common stock upon vesting. The RSUs are not entitled to voting rights until vested and generally vest over a one-to-three-year period, subject to the employees’ continued employment with the Company on each vesting date. The fair value of RSUs is based on the closing price of the Company’s common stock on the date of the grant and is amortized to share-based compensation expense over the estimated life of the award, generally the vesting period. Compensation expense recognized for RSUs issued under the 2016 Plan was $79,000 and $124,000 for the years ended March 31, 2025 and 2024, respectively.

COMMON, PREFERRED STOCK AND STOCKHOLDERS’ EQUITY

The Company has authorized a total of 60 million shares of which 50 million shares are authorized common stock and 10 million shares are authorized preferred stock. None of the preferred stock was issued or outstanding at March 31, 2025 and 2024. Under the terms of the Company’s Amended and Restated Articles of Incorporation, the Board of Directors is authorized to determine or alter the rights, preferences, privileges and restrictions of the Company’s authorized but unissued shares of preferred stock.

On December 15, 2023, the Company completed a private placement (the “Private Placement”) of an aggregate of 400,000 shares (the “Private Placement Shares”) of its common stock, par value $0.02 per share (the “Common Stock”), at a price of $1.00 per share for gross proceeds of $400,000. The Private Placement Shares were issued pursuant to the exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), provided by Section 4(a)(2) of the Securities Act to one investor, the Company’s Chairman of the Board, and pursuant to a Subscription Agreement (the “Subscription Agreement”), dated December 15, 2023.

EARNINGS (LOSS) PER SHARE

Basic loss per share is computed on the basis of the weighted average number of common shares outstanding. Diluted loss per share is computed on the basis of the weighted average number of common shares outstanding plus the potentially dilutive effect of outstanding stock options and unvested restricted stock units using the treasury stock method.

Table of Contents

Reconciliations between the numerator and the denominator of the basic and diluted loss per share computations for the fiscal years ended March 31, 2025 and 2024 are as follows:

	Net Loss (Numerator)			Shares (Denominator)		Per Share Amount
	(in thousands, except per share amounts)
Year ended March 31, 2025:
Basic and diluted loss per share	$	(3,203	)		7,071	$	(0.45	)
Year ended March 31, 2024:
Basic and diluted loss per share	$	(5,267	)		6,531	$	(0.81	)

Basic and diluted per share amounts are the same in periods of a net loss because common share equivalents are anti-dilutive when a net loss is recorded. Restricted stock units become dilutive within the period granted and remain dilutive until the units vest and are then included in the calculation of basic earnings per share.

12.

PROFIT SHARING AND 401(K) PLAN

The Company sponsors a profit sharing plan for all employees not covered under a separate management incentive plan. Under the profit sharing plan, a percentage determined by the Board of Directors of pre-tax profits on a quarterly basis may be allocated to non-management employees at management’s discretion. The profit sharing bonus may be distributed all in cash on an after-tax basis or distributed half in cash (on an after-tax basis) and the remainder deposited in an employee’s 401(k) account on a pre-tax basis. Employees may also make voluntary pre-tax contributions to their 401(k) accounts. There was no compensation expense under this plan for the fiscal years ended March 31, 2025 or 2024. Additionally, the Company has the discretion to make a retirement contribution to all employees individual 401(k) accounts equal to two percent of each employee’s base pay for each bi-weekly pay period on a pre-tax basis. Retirement expense under this plan was approximately $6,000 and $82,000 for the fiscal years ended March 31, 2025 and 2024, respectively.

SEGMENT REPORTING, PRODUCT LINE AND GEOGRAPHIC INFORMATION

Segment Reporting

Operating segments are identified as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company determined that based on the regularly reviewed and provided financial package to its Chief Executive Officer (the “CEO”) and Chief Financial Officer (the “CFO”), that the CEO and CFO together are its singular Chief Operating Decision Maker. Additionally, the Company determined that due to its sole focus on the cultivation and production of microalgal products, the Company views its operations and manages its business as one operating and reportable segment focused on the manufacture and distribution of natural products derived from microalgae, astaxanthin and spirulina.

The CEO and CFO together, are the chief operating decision maker (the “CODM”) and manages the business based on consolidated financial results and use consolidated net income or loss, including significant operating expenses, for the purpose of assessing performance, allocating resources across departments and making operating decisions.

The CODM uses consolidated income (loss) from operations and operating expenses to monitor actual results versus budget and prior year’s results, which facilitates the assessment of the Company’s performance in line with the Company’s strategic goals. Monitoring of budget versus actual results are used in assessing performance of the segment and in establishing management’s compensation.

All revenue, operating expenses and assets attributed to this one segment are reflected in the consolidated financial statements. The Company’s significant segment expenses align with the categories on the consolidated statements of operations. The measure of segment assets is reported on the consolidated balance sheets as total consolidated assets. All segment long-lived assets are located in the United States of America.

In assessing the valuation allowance for deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Ultimately, the realization of deferred tax assets will depend on the existence future taxable income during the periods. In making this assessment, management considers past operating results, the scheduled reversal of deferred tax liabilities, estimates of future taxable income and tax planning strategies.

As of March 31, 2025 and 2024, the Company has concluded that a valuation allowance was appropriate in light of the significant negative evidence, which was objective and verifiable and primarily due to the cumulative losses in recent years.

While the Company’s long-term financial outlook remains positive, the Company concluded that its ability to rely on its long-term outlook as to future taxable income was limited due to the relative weight of the negative evidence from its recent cumulative losses. The Company’s conclusion regarding the need for a valuation allowance against its deferred tax assets could change in the future based on improvements in operating performance, which may result in the full or partial reversal of the valuation allowance.

RELATED-PARTY TRANSACTIONS AND BALANCES

In April 2019, the Company obtained an unsecured subordinated loan from Skywords Family Foundation, Inc. (“Skywords”) in the principal amount of $1,500,000 pursuant to a Promissory Note (the “Skywords Note”) executed by the Company in favor of Skywords. Skywords is controlled by the Company’s Chairman of the Board of Directors and largest stockholder. The Skywords Note bore interest at a rate of 1% plus the prime rate (as published by the Wall Street Journal), which was recalculated and payable on a quarterly basis. The principal amount and any accrued and unpaid interest were originally due and payable on April 12, 2021. The proceeds of the Skywords Note were used to pay down accounts payable and for general operating capital purposes.

On April 12, 2021, the Company entered into an Amended and Restated Promissory Note (the “Skywords Amended Note”) with Skywords. The Company and Skywords agreed to amend, restate, replace and otherwise modify without novation, the Skywords Note in order to convert $500,000 of the outstanding principal amount into revolving loans that may be prepaid and reborrowed from time to time in principal amounts not to exceed $500,000, extend the maturity date by three years, adjust the interest rate to reflect a floor of 5% and secure Skywords’ interest by granting a security interest in substantially all of the Company’s personal property assets, subject to limited exceptions (the “Collateral”). On April 12, 2021, concurrently with the conversion, the Company repaid in cash to Skywords the principal amount of $500,000 plus accrued interest to date of $1,900. The Skywords Amended Note bears interest at a rate of 1% plus the prime rate (as published by the Wall Street Journal), which will be recalculated and payable on a quarterly basis, provided that at no time shall the annual interest rate be less than 5%. The Company may prepay the Skywords Amended Note at any time without penalty.

On April 12, 2021, in connection with the grant of a security interest in the Collateral, the Company also entered into an Intercreditor and Subordination Agreement with the Bank and Skywords. The Company is indebted to the Bank pursuant to two Term Loans and a Credit Agreement, each of which granted the Bank a security interest in substantially all of the Company’s personal property assets. The Bank’s security interest in the Company’s personal property assets ranks senior to Skywords’ security interest in the Collateral, and the Intercreditor and Subordination Agreement generally governs the relationship between the Bank and Skywords as secured lenders to the Company and includes customary terms.

Table of Contents

On December 14, 2022, the Company entered into a First Amendment (the “Amendment”) to the Skywords Amended Note. The Amendment extends the maturity date to April 12, 2025 and increases the revolving amount that the Company may borrow from time to time under the Skywords Note from $500,000 to $1,000,000.

On August 14, 2023, the Company entered into a Second Amendment (the “Second Amendment”) to the Skywords Amended Note. The Second Amendment increased the revolving amount that the Company may borrow from time to time under the Skywords Amended Note from $1,000,000 to $2,000,000.

On August 9, 2024, the Company entered into the Third Amendment (the “Third Amendment”) to the Skywords Amended Note. The Third Amendment extends the maturity date to April 12, 2026 and increased the revolving amount that the Company may borrow from time to time under the Skywords Note from $2,000,000 to $4,000,000. The Third Amendment also extended the maturity date of the Skywords Note to April 12, 2027.

At both March 31, 2025 and 2024, the Skywords Note principal balance was $1,000,000, and was included in long-term debt on the consolidated balance sheets. At March 31, 2025 and 2024, the balance on the Revolver was $3,000,000 and $1,250,000, respectively, and was included in line of credit – related party on the consolidated balance sheets. At March 31, 2025 and 2024, the interest rates were 7.5% and 8.5%, respectively.

On May 2, 2025, the Company entered into the Fourth Amendment (the “Fourth Amendment”) to the Skywords Amended Note. To assist in reducing the Company’s ongoing cash outflows, the Fourth Amendment allows the Company to elect to pay the interest accrued during the fiscal year ended March 31, 2026 in the form of its common stock in lieu of cash. All other terms of the Skywords Amended Note remain the same.

The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our management evaluated the effectiveness of our internal control over financial reporting as of March 31, 2025. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in “Internal Control - Integrated Framework” (2013 Framework). Based on our assessment, using those criteria, management concluded that our internal control over financial reporting was effective as of March 31, 2025.

Changes in Internal Control over Financial Reporting.

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2025 that has materially affected, or was reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls.

Our management, including our CEO and CFO, do not expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent all errors and all fraud. A control system no matter how well designed and implemented, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs.

The inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, or by collusion of two or more people. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
